Ubuntu Security Notice USN-1765-1

Ubuntu Security Notice USN-1765-1
Posted Mar 19, 2013
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1765-1 - 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 11.10. Various other issues were also addressed.

apache2 vulnerabilities
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Several security issues were fixed in the Apache HTTP Server.

Software Description:
- apache2: Apache HTTP server

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.
(CVE-2013-1048)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
apache2.2-common 2.2.22-6ubuntu2.2

Ubuntu 12.04 LTS:
apache2.2-common 2.2.22-1ubuntu1.3

Ubuntu 11.10:
apache2.2-common 2.2.20-1ubuntu1.4

Ubuntu 10.04 LTS:
apache2.2-common 2.2.14-5ubuntu8.11

Ubuntu 8.04 LTS:
apache2.2-common 2.2.8-1ubuntu0.25

In general, a standard system update will make all the necessary changes.
