TITLE:
GIT Pathname Processing Multiple Buffer Overflows

SECUNIA ADVISORY ID:
SA31347

VERIFY ADVISORY:
http://secunia.com/advisories/31347/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
GIT 1.x
http://secunia.com/product/7172/

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

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.

The vulnerabilities are reported in version 1.5.6.3. Prior versions
may also be affected.

SOLUTION:
Update to version 1.5.6.4.
http://www.kernel.org/pub/software/scm/git/
