Ubuntu 4.10 : XML library vulnerabilities (USN-10-1)

critical Nessus Plugin ID 20485

Synopsis

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

Description

Several buffer overflows have been discovered in libxml2's FTP connection and DNS resolution functions. Supplying very long FTP URLs or IP addresses might result in execution of arbitrary code with the privileges of the process using libxml2.

Since libxml2 is used in packages like php4-imagick, the vulnerability also might lead to privilege escalation, like executing attacker supplied code with a web server's privileges.

However, this does not affect the core XML parsing code, which is what the majority of programs use this library for.

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.

Solution

Update the affected packages.
