Ubuntu Security Notice (C) 2013 Canonical, Inc. / NASL script (C) 2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
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.
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
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).
Update the affected apache2.2-common package.
