Test ID:
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0779
The remote host is missing updates announced in
advisory RHSA-2010:0779.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues:

* Information leak flaws were found in the Linux kernel Traffic Control
Unit implementation. A local attacker could use these flaws to cause the
kernel to leak kernel memory to user-space, possibly leading to the
disclosure of sensitive information. (CVE-2010-2942, Moderate)

* A flaw was found in the tcf_act_police_dump() function in the Linux
kernel network traffic policing implementation. A data structure in
tcf_act_police_dump() was not initialized properly before being copied to
user-space. A local, unprivileged user could use this flaw to cause an
information leak. (CVE-2010-3477, Moderate)

* A missing upper bound integer check was found in the sys_io_submit()
function in the Linux kernel asynchronous I/O implementation. A local,
unprivileged user could use this flaw to cause an information leak.
(CVE-2010-3067, Low)

Red Hat would like to thank Tavis Ormandy for reporting CVE-2010-3067.

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.

Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
