USN-89-1: XML library vulnerabilities
===========================================================
Ubuntu Security Notice USN-89-1 February 28, 2005
libxml vulnerabilities
CAN-2004-0989
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
The following packages are affected:
libxml1
The problem can be corrected by upgrading the affected package to
version 1:1.8.17-8ubuntu0.1. In general, a standard system upgrade is
sufficient to effect the necessary changes.
Details follow:
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.
