Ubuntu 6.06 LTS / 6.10 / 7.04 : apache2 vulnerabilities (USN-499-1)

Medium Nessus Plugin ID 28102


The remote Ubuntu host is missing one or more security-related patches.


Stefan Esser discovered that mod_status did not force a character set, which could result in browsers becoming vulnerable to XSS attacks when processing the output. If a user were tricked into viewing server status 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. By default, mod_status is disabled in Ubuntu. (CVE-2006-5752)

Niklas Edmundsson discovered that the mod_cache module could be made to crash using a specially crafted request. A remote user could use this to cause a denial of service if Apache was configured to use a threaded worker. By default, mod_cache is disabled in Ubuntu.

A flaw was discovered in the signal handling of Apache. A local attacker could trick Apache into sending SIGUSR1 to other processes.
The vulnerable code was only present in Ubuntu Feisty. (CVE-2007-3304).

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.


Update the affected packages.
