The remote Red Hat host is missing one or more security updates.
Updated kernel packages that fix two security issues and one bug are
now available for Red Hat Enterprise Linux 5.6 Extended Update
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
The kernel packages contain the Linux kernel, the core of any Linux
This update fixes the following security issues :
* A flaw was found in the way socket buffers (skb) requiring TSO (TCP
segment offloading) were handled by the sfc driver. If the skb did not
fit within the minimum-size of the transmission queue, the network
card could repeatedly reset itself. A remote attacker could use this
flaw to cause a denial of service. (CVE-2012-3412, Important)
* A buffer overflow flaw was found in the hfs_bnode_read() function in
the HFS Plus (HFS+) file system implementation in the Linux kernel. A
local user able to mount a specially crafted HFS+ file system image
could use this flaw to cause a denial of service or escalate their
privileges. (CVE-2012-2319, Low)
Red Hat would like to thank Ben Hutchings of Solarflare (tm) for
This update also fixes the following bug :
* Some subsystems clear the TIF_SIGPENDING flag during error handling
in fork() paths. Previously, if the flag was cleared, the
ERESTARTNOINTR error code could be returned. The underlying source
code has been modified so that the error code is no longer returned.
Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect.
