Cscope Security Update (RHSA-2009-1101)
cscope security update (RHSA-2009-1101) Original Release Date: June 16, 2009 Last Revised: June 16, 2009 Number: ASA-2009-236 Risk Level: None Advisory Version: 1.0 Advisory Status: Final 1. Overview: cscope is a mature, ncurses-based, C source-code tree browsing tool. Multiple buffer overflow flaws were found in cscope. An attacker could create a specially crafted source code file that could cause cscope to crash or, possibly, execute arbitrary code when browsed with cscope. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2004-2541, CVE-2006-4262, CVE-2009- 0148 and CVE-2009-1577 to these issues. Note: This advisory is specific to RHEL3 and RHEL4. No Avaya system products are vulnerable, as cscope is not installed by default. More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux: · https://rhn.redhat.com/errata/RHSA-2009-1101.html 2. Avaya System Products using RHEL3 or RHEL4 with cscope installed: None 3. Avaya Software-Only Products: Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform. In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.

Using Cscope in Vim
How to incorporate Cscope functionality into VIM. It also supports the use of the cursor to select source code symbols in VIM where you can type custom keystrokes to invoke powerful Cscope functionality. Not only that, it will allow you to invoke Cscope symbols from within any directory in your source code tree. That is because the Cscope database will be built from source- code file path-names referenced from your root directory instead of the standard present directory if you built the Cscope file without the necessary trickery. OS/ program requirements Cscope must be installed on your system. If you don’t have it, then install it be typing in the Terminal ‘yum install cscope’ if running Fedora or ‘sudo apt-get cscope’ if you are running Ubuntu. Note: You must have at least VIM 6.x for this to work correctly. Setting it up You must have cscope_maps.vim. This file should be located in ~/.vim/plugin. If this directory does not exist, then create it. Step 1) Add the .vim plugin directory to your $PATH. Add these lines to the end of your ~/.bash_profile or ~/.bashrc file. PATH=$PATH:$HOME/.vim/plugin EDITOR="vim" Step 2) Add the following code to the bottom of your ~/.bashrc file. This is the function and alias which builds the cscope database. This one is setup to find .c and .h files. Change for the file extensions that are in your source code. function build_cscope_db_func() { local PROJDIR=$PWD cd / find $PROJDIR –name ‘*.c’ –o –name ‘*.h’ > $PROJDIR/cscope.files cd $PROJDIR cscope –Rbkq } alias csbuild=‘build_cscope_db_func’ Step 3) Launch another bash session by typing ‘bash’ at the command prompt.

Vim for C Programmers
Vim for C Programmers http://interactive.linuxjournal.com/node/8289/print Vim for C Programmers By Girish Venkatachalam Created 2005-10-31 02:00 Thank you for subscribing to Linux Journal. You don't have to move to an integrated development environment to get luxury coding features. From variable autocompletions all the way up to integration with ctags and make, Vim makes a C programmer's life easier and more productive. Vim is an extremely powerful editor with a user interface based on Bill Joy's almost 30-year-old vi, but with many new features. The features that make Vim so versatile also sometimes make it intimidating for beginners. This article attempts to level the learning curve with a specific focus on C programming. make and the Compile-Test-Edit Cycle A typical programmer's routine involves compiling and editing programs until the testing proves that the program correctly does the job it is supposed to do. Any mechanism that reduces the rigor of this cycle obviously makes any programmer's life easier. Vim does exactly that by integrating make with Vim in such a way that you don't have to leave the editor to compile and test the program. Running :make from inside of Vim does the job for you, provided a makefile is in the current directory. You can change the directory from inside of Vim by running :cd. To verify where you are, use :pwd. In case you are using FreeBSD and want to invoke gmake instead of make from the command line, all you have to do is enter :set makeprg=gmake.
