RHEL 3 / 4 / 5 : libxml2 (RHSA-2008:0884)
Critical Nessus Plugin ID 34190
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated libxml2 packages that fix a security issue are now available for Red Hat Enterprise Linux 3, 4, and 5.
This update has been rated as having important security impact by the Red Hat Security Response Team.
The libxml2 packages provide a library that allows you to manipulate XML files. It includes support to read, modify, and write XML and HTML files.
A heap-based buffer overflow flaw was found in the way libxml2 handled long XML entity names. If an application linked against libxml2 processed untrusted malformed XML content, it could cause the application to crash or, possibly, execute arbitrary code.
All users of libxml2 are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue.
SolutionUpdate the affected libxml2, libxml2-devel and / or libxml2-python packages.
