Synopsis: Important: kernel security and bug fix update
Advisory ID: SLSA-2014:0475-1
Issue Date: 2014-05-07
CVE Numbers: CVE-2013-6383
 CVE-2014-0077
 CVE-2014-2523
--

* A flaw was found in the way the Linux kernel's netfilter connection
tracking implementation for Datagram Congestion Control Protocol (DCCP)
packets used the skb_header_pointer() function. A remote attacker could
use this flaw to send a specially crafted DCCP packet to crash the system
or, potentially, escalate their privileges on the system. (CVE-2014-2523,
Important)

* A flaw was found in the way the Linux kernel's Adaptec RAID controller
(aacraid) checked permissions of compat IOCTLs. A local attacker could use
this flaw to bypass intended security restrictions. (CVE-2013-6383,
Moderate)

* A flaw was found in the way the handle_rx() function handled large
network packets when mergeable buffers were disabled. A privileged guest
user could use this flaw to crash the host or corrupt QEMU process memory
on the host, which could potentially result in arbitrary code execution on
the host with the privileges of the QEMU process. (CVE-2014-0077,
Moderate)

The system must be rebooted for this update to take effect.
