Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. Description: 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 aDTD. 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at 5.
