3. Problem description:
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 an attacker 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 an attacker 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 CAN-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 an attacker is able to find an application using libxml that parses remote resources and allows 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 CAN-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.
