RHEL 3 / 4 / 5 : libxml and libxml2 (RHSA-2009:1206)
medium Nessus Plugin ID 40544
Synopsis
The remote Red Hat host is missing one or more security updates.Description
Updated libxml and libxml2 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.This update has been rated as having moderate security impact by the Red Hat Security Response Team.
libxml is a library for parsing and manipulating XML files. A Document Type Definition (DTD) defines the legal syntax (and also which elements can be used) for certain types of files, such as XML files.
A stack overflow flaw was found in the way libxml processes the root XML document element definition in a DTD. A remote attacker could provide a specially crafted XML file, which once opened by a local, unsuspecting user, would lead to denial of service (application crash). (CVE-2009-2414)
Multiple use-after-free flaws were found in the way libxml parses the Notation and Enumeration attribute types. A remote attacker could provide a specially crafted XML file, which once opened by a local, unsuspecting user, would lead to denial of service (application crash). (CVE-2009-2416)
Users should upgrade to these updated packages, which contain backported patches to resolve these issues. For Red Hat Enterprise Linux 3, they contain backported patches for the libxml and libxml2 packages. For Red Hat Enterprise Linux 4 and 5, they contain backported patches for the libxml2 packages. The desktop must be restarted (log out, then log back in) for this update to take effect.
