Debian Security Update - Php5 Debian Security Update - php5 AlienVault ID: ENG-107845 Description: An issue was discovered in PHP before 5.6.35, 7.0.x before 7.0.29, 7.1.x before 7.1.16, and 7.2.x before 7.2.4. Dumpable FPM child processes allow bypassing opcache access controls because fpm_unix.c makes a PR_SET_DUMPABLE prctl call, allowing one user (in a multiuser environment) to obtain sensitive information from the process memory of a second user's PHP applications by running gcore on the PID of the PHP-FPM worker process. CVE ID: CVE-2018-10545 CVSS: 3.7 Debian Security Update - php5 AlienVault ID: ENG-107845 Description: An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. An infinite loop exists in ext/iconv/iconv.c because the iconv stream filter does not reject invalid multibyte sequences. CVE ID: CVE-2018-10546 CVSS: 3.7 Debian Security Update - php5 AlienVault ID: ENG-107845 Description: An issue was discovered in ext/phar/phar_object.c in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. There is Reflected XSS on the PHAR 403 and 404 error pages via request data of a request for a .phar file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-5712. CVE ID: CVE-2018-10547 CVSS: 3.2 Debian Security Update - php5 AlienVault ID: ENG-107845 Description: An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. ext/ldap/ldap.c allows remote LDAP servers to cause a denial of service (NULL pointer dereference and application crash) because of mishandling of the ldap_get_dn return value. CVE ID: CVE-2018-10548 CVSS: 3.7 Debian Security Update - php5 AlienVault ID: ENG-107845 Description: An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. exif_read_data in ext/exif/exif.c has an out-of-bounds read for crafted JPEG data because exif_iif_add_value mishandles the case of a MakerNote that lacks a final '\0' character. CVE ID: CVE-2018-10549 CVSS: 5.0 Debian Security Update - php5 AlienVault ID: ENG-107845 Description: In PHP through 5.6.33, 7.0.x before 7.0.28, 7.1.x through 7.1.14, and 7.2.x through 7.2.2, there is a stack-based buffer under-read while parsing an HTTP response in the php_stream_url_wrap_http_ex function in ext/standard/http_fopen_wrapper.c. This subsequently results in copying a large string. CVE ID: CVE-2018-7584 CVSS: 6.2 Debian Security Update - libgcrypt20 AlienVault ID: ENG-107857 Description: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. CVE ID: CVE-2018-0495 CVSS: 1.4 Debian Security Update - tiff AlienVault ID: ENG-107838 Description: In LibTIFF 4.0.8, there is a denial of service vulnerability in the TIFFOpen function. A crafted input will lead to a denial of service attack. During the TIFFOpen process, td_imagelength is not checked. The value of td_imagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the _TIFFCheckMalloc function is called based on td_imagelength. If we set the value of td_imagelength close to the amount of system memory, it will hang the system or trigger the OOM killer. CVE ID: CVE-2017-11613 CVSS: 4.3 Debian Security Update - tiff AlienVault ID: ENG-107838 Description: The TIFFWriteDirectorySec() function in tif_dirwrite.c in LibTIFF through 4.0.9 allows remote attackers to cause a denial of service (assertion failure and application crash) via a crafted file, a different vulnerability than CVE-2017-13726.= CVE ID: CVE-2018-10963 CVSS: 4.3 Debian Security Update - tiff AlienVault ID: ENG-107838 Description: In LibTIFF 4.0.9, there is an uncontrolled resource consumption in the TIFFSetDirectory function of tif_dir.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tif file. This occurs because the declared number of directory entries is not validated against the actual number of directory entries. CVE ID: CVE-2018-5784 CVSS: 4.3 Debian Security Update - tiff AlienVault ID: ENG-107838 Description: A NULL Pointer Dereference occurs in the function TIFFPrintDirectory in tif_print.c in LibTIFF 4.0.9 when using the tiffinfo tool to print crafted TIFF information, a different vulnerability than CVE-2017-18013. (This affects an earlier part of the TIFFPrintDirectory function that was not addressed by the CVE-2017-18013 patch.) CVE ID: CVE-2018-7456 CVSS: 4.3 Debian Security Update - tiff AlienVault ID: ENG-107838 Description: In LibTIFF 4.0.9, a heap-based buffer overflow occurs in the function LZWDecodeCompat in tif_lzw.c via a crafted TIFF file, as demonstrated by tiff2ps.\ CVE ID: CVE-2018-8905 CVSS: 5.0 Debian Security Update - libsoup2.4 AlienVault ID: ENG-107846 Description: The get_cookies function in soup-cookie-jar.c in libsoup 2.63.2 allows attackers to have unspecified impact via an empty hostname CVE ID: CVE-2018-12910 CVSS: 6.4 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. CVE ID: CVE-2017-5715 CVSS: 4.2 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. CVE ID: CVE-2017-5753 CVSS: 4.2 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: ** DISPUTED ** Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel heap pages to the userspace. This has been fixed upstream in https://github.com/torvalds/linux/commit/a45b599ad808c3c982fdcdc12b0b8611c2f92824 already. The problem has limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties dispute the relevance of this report, noting that the requirement for an attacker to have both the CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it "virtually impossible to exploit." CVE ID: CVE-2018-1000204 CVSS: 6.3 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: The Linux kernel before version 4.11 is vulnerable to a NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response is mishandled during session recovery. CVE ID: CVE-2018-1066 CVSS: 5.9 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest. CVE ID: CVE-2018-10853 CVSS: RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided. Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers. CVE ID: CVE-2018-1093 CVSS: 5.3 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: The cdrom_ioctl_media_changed function in drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6 allows local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory. CVE ID: CVE-2018-10940 CVSS: AlienVault Note: Not affected. Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: Linux kernel before version 4.16-rc7 is vulnerable to a null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in that allows a local user to cause a denial of service by a number of certain crafted system calls. CVE ID: CVE-2018-1130 CVSS: 3.6 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in the Linux kernel through 4.16.12 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact because sense buffers have different sizes at the CDROM layer and the SCSI layer, as demonstrated by a CDROMREADMODE2 ioctl call. CVE ID: CVE-2018-11506 CVSS: 5.3 Debian Security Update - Linux(Kernel) AlienVault ID: ENG-107854 Description: In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in JFS can be triggered by calling setxattr twice with two different extended attribute names on the same file.

  • Fancy Filesystems a Look at Some of the Many Options We Have for Serving up Data to Users
    Fancy Filesystems A look at some of the many options we have for serving up data to users. With thanks to Winnie, Sam, Rob and Raul. Disclaimer - I don’t know much, but this is about starting conversations. Old School (1) - NFS/ClassicSE style ● A single server with a chunky volume, presented over nfs or behind a single protocol endpoint. ○ I’d say this is how we did things “back in the day”, but I’d put money on everyone in this room having an nfs box or two sitting in their cluster - or even back at home! ○ The ClassicSE is less common. ● Retro is back in fashion though, and that’s not necessarily a bad thing. ○ It’s easy to have over 100TB in a 2U box. ○ Decent in-rack networks are commonplace, so these boxes can be well connected. ○ Easy to admin, well understood. ○ Xroot (or XCache) servers are the new ClassicSE ● Of course there are some limitations and concerns. ○ IOPs, Bandwidth and Resilience are all factors when dealing with single servers. Old School (2) - The not so classic SEs. The early naughties saw sites deploy what is a very griddy solution for their storage with DPM and DCache SEs. ● From a distance they both look very similar - protocol gateways on every pool server, a single metadata server pulling things together in a giant virtual filesystem. ● Very grid-specific solution. ● Easiest access via gfal (or lcg…) tools. ● Protocols very grid focused. Rise of ZFS In recent years some of us have been ditching raid cards for ZFS. Raid 6 is dead, long live RaidZ3! ● Although I for one do not think I’m leveraging enough of the ZFS features (or whether or not we can even leverage them).

  • Newest Trends in High Performance File Systems
    Newest Trends in High Performance File Systems — Seminarbericht — Arbeitsbereich Wissenschaftliches Rechnen Fachbereich Informatik Fakultät für Mathematik, Informatik und Naturwissenschaften Universität Hamburg Vorgelegt von: Elena Bergmann E-Mail-Adresse: [email protected] Matrikelnummer: 6525540 Studiengang: Informatik Betreuer: Julian Kunkel Hamburg, den 30.03.2016 Abstract File Systems are important for storage devices and therefore also important for high computing. This paper describes file systems and parallel file systems in general and the Sirocco File System in detail. The development of Sirocco shows how it could handle the big gap between produced data from the processor and the data rate that can be stored by current storage systems. Sirocco is inspired by loose coupling of peer-to-peer systems, where clients can join and exit the network any time without endangering the stability of the network. The user gets the ability to chose their storage location and the system replicates files and servers to maintain its health.

  • From Online Social Network Analysis to a User-Centric Private Sharing System
    From online social network analysis to a user-centric private sharing system by © Arastoo Bozorgi A thesis submitted to the School of Graduate Studies in partial fulfilment of the requirements for the degree of Doctor of Philosophy Department of Computer Science Memorial University of Newfoundland July 2020 St. John’s Newfoundland Abstract Online social networks (OSNs) have become a massive repository of data con- structed from individuals’ inputs: posts, photos, feedbacks, locations, etc. By analyzing such data, meaningful knowledge is generated that can affect individuals’ beliefs, desires, happiness and choices — a data circulation started from individuals and ended in individuals! The OSN owners, as the one authority having full control over the stored data, make the data available for research, advertisement and other purposes. However, the individuals are missed in this circle while they generate the data and shape the OSN structure. In this thesis, we started by introducing approximation algorithms for finding the most influential individuals in a social graph and modeling the spread of information. To do so, we considered the communities of individuals that are shaped in a social graph. The social graph is extracted from the data stored and controlled centrally, which can cause privacy breaches and lead to individuals’ concerns. Therefore, we introduced UPSS: the user-centric private sharing system, in which the individuals are considered as the real data owners and provides secure and private data sharing on untrusted servers. The UPSS’s public API allows the application developers to implement appli- cations as diverse as OSNs, document redaction systems with integrity properties, censorship-resistant systems, health care auditing systems, distributed version con- trol systems with flexible access controls and a filesystem in userspace.
