Ubuntu Security Notice USN-10-1
29th October, 2004
XML library vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 4.10
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 4.10:
- libxml2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
