PACKAGE : vim SUMMARY : Arbitrary commands execution through modelines DATE : 2004-02-10 17:47:00 ID : CLA-2004:812 RELEVANT RELEASES : 8

- -------------------------------------------------------------------------

DESCRIPTION Vim is a highly configurable text editor. It is an improved version of the vi editor distributed with most UNIX systems. Georgi Guninski found[1] a vulnerability[2] in vim that can be exploited to execute arbitrary commands when the user opens a text file specially crafted by an attacker. The vulnerability resides in the "modelines" feature, which allows one to place some VIM commands inside of a text file. This update includes a new version of vim (6.1+patches) which, besides the fix for the aforementioned vulnerability, contains several other bug fixes. The vim package distributed with Conectiva Linux 9 (vim-*-6.1-27650cl) is already patched and therefore not vulnerable to this issue.
