"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."
