| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2010:0758.
The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* The compat_alloc_user_space() function in the Linux kernel 32/64-bit
compatibility layer implementation was missing sanity checks. This function
could be abused in other areas of the Linux kernel if its length argument
can be controlled from user-space. On 64-bit systems, a local, unprivileged
user could use this flaw to escalate their privileges. (CVE-2010-3081,
Important)
* 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 Ben Hawkes for reporting CVE-2010-3081, and
Tavis Ormandy for reporting CVE-2010-3067.
Users are advised to upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be rebooted for
this update to take effect.
