| Descripción: | Description:
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.
