Vulnerability Assessment Details

RHSA-2004-650: libxml

Vulnerability Assessment Summary
Check for the version of the libxml packages

Detailed Explanation for this Vulnerability Assessment

An updated libxml package that fixes multiple buffer overflows is now
available.

The libxml package contains a library for manipulating XML files.

Multiple buffer overflow bugs have been found in libxml versions prior to
2.6.14. If a possible hacker can trick a user into passing a specially crafted
FTP URL or FTP proxy URL to an application that uses the vulnerable
functions of libxml, it could be possible to execute arbitrary code.
Additionally, if a possible hacker can return a specially crafted DNS request to
libxml, it could be possible to execute arbitrary code. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-0989 to this issue.

Yuuichi Teranishi discovered a flaw in libxml versions prior to 2.6.6.
When fetching a remote resource via FTP or HTTP, libxml uses special
parsing routines. These routines can overflow a buffer if passed a very
long URL. If a possible hacker is able to find an application using libxml that
parses remote resources and permits them to influence the URL, then this
flaw could be used to execute arbitrary code. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0110
to this issue.

All users are advised to upgrade to this updated package, which contains
backported patches and is not vulnerable to these issues.
