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)

It was discovered that the Git web interface (gitweb) did not properly restrict
the diff.external configuration parameter. A local attacker could exploit this
issue and execute arbitrary code with the privileges of the Git web server.
This issue only applied to Ubuntu 8.04 LTS and 8.10. (CVE-2008-5916)");
