New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Red Hat host is missing one or more security updates.


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

[Updated 24 May 2005] Multilib packages have been added to this advisory

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 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 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 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.


Update the affected libxml and / or libxml-devel packages.
