Details
Niels Heinen discovered that multiple modules incorrectly sanitized certain
strings, which could result in browsers becoming vulnerable to cross-site
scripting attacks when processing the output. With cross-site scripting
vulnerabilities, if a user were tricked into viewing server output during a
crafted server request, a remote attacker could exploit this to modify the
contents, or steal confidential data (such as passwords), within the same
domain. (CVE-2012-3499, CVE-2012-4558)
It was discovered that the mod_proxy_ajp module incorrectly handled error
states. A remote attacker could use this issue to cause the server to stop
responding, resulting in a denial of service. This issue only applied to
Ubuntu 8.04 LTS, Ubuntu 10.04 LTS and Ubuntu 11.10. (CVE-2012-4557)

It was discovered that the apache2ctl script shipped in Ubuntu packages
incorrectly created the lock directory. A local attacker could possibly use
this issue to gain privileges. The symlink protections in Ubuntu 11.10 and
later should reduce this vulnerability to a denial of service.
