Ubuntu 4.10 : libxml vulnerabilities (USN-89-1)

Description

Several buffer overflows have been discovered in libxml'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 libxml.

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

Note: The same vulnerability was already fixed for libxml2 in USN-10-1.

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.
