1. Summary:
Updated xen packages that fix one security issue are now available for Red Hat Enterprise Linux 5.
Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
2. Relevant releases/architectures:
RHEL Desktop Multi OS (v. 5 client) - i386, x86_64 RHEL Virtualization (v. 5 server) - i386, ia64, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
3. Description:
The xen packages contain administration tools and the xend service for managing the kernel-xen kernel for virtualization on Red Hat Enterprise Linux.
A heap buffer overflow flaw was found in the way QEMU's NE2000 NIC emulation implementation handled certain packets received over the network. A privileged user inside a guest could use this flaw to crash the QEMU instance (denial of service) or potentially execute arbitrary code on the host. (CVE-2015-5279)
Red Hat would like to thank Qinghao Tang of QIHU 360 Inc. for reporting this issue.
All xen users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, all running fully-virtualized guests must be restarted for this update to take effect.
