Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that Git did not properly handle long file paths. If
a user were tricked into performing commands on a specially crafted
Git repository, an attacker could possibly execute arbitrary code with
the privileges of the user invoking the program. (CVE-2008-3546)

It was discovered that the Git web interface (gitweb) did not
correctly handle shell metacharacters when processing certain
commands. A remote attacker could send specially crafted commands to
the Git server and execute arbitrary code with the privileges of the
Git web server. This issue only applied to Ubuntu 7.10 and 8.04 LTS.
(CVE-2008-5516, CVE-2008-5517)
