Description

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. (CVE-2013-1048).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
