Pardus Linux Security Advisory 2008-19            security@pardus.org.tr
------------------------------------------------------------------------
       Date: 2008-08-07
   Severity: 2
       Type: Remote
------------------------------------------------------------------------

Summary
=======

Some vulnerabilities have been reported in GIT, which can potentially be
exploited by malicious people to compromise a user's system.


Description
===========

The vulnerabilities are  caused  due  to  boundary  errors  in  various
functions when processing overly long repository pathnames. These can be
exploited to cause stack-based buffer overflows by tricking a user into
running e.g. "git-diff" or "git-grep" against a  repository  containing
pathnames that are larger than  the  "PATH_MAX"  value  on  the  user's
system.



Successful exploitation may allow execution of arbitrary code.


Affected packages:

   Pardus 2008:
     git, all before 1.5.6.4-66-3
     git-emacs, all before 1.5.6.4-66-3
     gitweb, all before 1.5.6.4-66-3

   Pardus 2007:
     git, all before 1.5.6.4-66-51
     git-emacs, all before 1.5.6.4-66-25
     gitweb, all before 1.5.6.4-66-27



Resolution
==========

There are update(s) for git, git-emacs, gitweb. You can update them via
Package Manager or with a single command from console:

   Pardus 2008:
     pisi up git git-emacs gitweb
