    Mesačný prehľad kritických zraniteľností Mesačný prehľad kritických zraniteľností Máj 2018 1. Operačné systémy Microsoft Windows V máji spoločnosť Microsoft opravila 4 kritické zraniteľnosti operačného systému Microsoft Windows. Zraniteľnosti CVE-2018-0959 a CVE-2018-0961 môžu spôsobiť vykonanie škodlivého kódu na diaľku. Prvá z nich je spôsobená nesprávnym overovaním vstupu Windows Hyper-V na serveri od autentifikovaného používateľa na hostiteľskom operačnom systéme. Druhá sa týka overovania paketových dát v SMB protokole systému Windows Hyper-V. Na zneužitie týchto zraniteľností musí útočník spustiť špeciálne vytvorenú aplikáciu, ktorá umožní zneužitie týchto zraniteľností. Úspešný útočník následne môže vykonať ľubovoľný kód pomocou Windows Hyper-V. Našli sa aj zraniteľnosti CVE-2018-8120 a CVE-2018-8174 taktiež umožňujúce vzdialené vykonávanie kódu či zvýšenie privilégií, ktoré sú bližšie popísané aj v našom varovaní.

  • A Secure Searcher for End-To-End Encrypted Email Communication
    A secure searcher for end-to-end encrypted email communication Balamaruthu Mani Dissertation 2015 Erasmus Mundus MSc in Dependable Software Systems Department of Computer Science National University of Ireland, Maynooth Co. Kildare, Ireland A dissertation submitted in partial fulfilment of the requirements for the Erasmus Mundus MSc Dependable Software Systems Head of Department: Dr Adam Winstanley Supervisor: Professor Barak A. Pearlmutter 8-June-2015 Word Count: 19469 1 Abstract Email has become a common mode of communication for confidential personal as well as business needs. There are different approaches to authenticate the sender of an email message at the receiver‟s client and ensure that the message can be read only by the intended recipient. A typical approach is to use an email encryption standard to encrypt the message on the sender‟s client and decrypt it on the receiver‟s client for secure communication. A major drawback of this approach is that only the encrypted email messages are stored in the mail servers and the default search does not work on encrypted data. This project details an approach that could be adopted for securely searching email messages protected using end-to-end encrypted email communication. This project proposes an overall design for securely searching encrypted email messages and provides an implementation in Java based on a cryptographically secure Bloom filter technique to create a secure index. The implemented library is then integrated with an open source email client to depict its usability in a live environment. The technique and the implemented library are further evaluated for security and scalability while allowing remote storage of the created secure index.
