Test ID:1.3.6.1.4.1.25623.1.0.870705
Category:Red Hat Local Security Checks
Title:RedHat Update for kernel RHSA-2012:0481-01
Summary:The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.

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

This update fixes the following security issues:

* Numerous reference count leaks were found in the Linux kernel's block
layer I/O context handling implementation. This could allow a local,
unprivileged user to cause a denial of service. (CVE-2012-0879,
Moderate)

* A flaw was found in the Linux kernel's cifs_lookup() implementation.
POSIX open during lookup should only be supported for regular files. When
non-regular files (for example, a named (FIFO) pipe or other special files)
are opened on lookup, it could cause a denial of service. (CVE-2012-1090,
Moderate)

* It was found that the Linux kernel's register set (regset) common
infrastructure implementation did not check if the required get and set
handlers were initialized. A local, unprivileged user could use this flaw
to cause a denial of service by performing a register set operation with a
ptrace() PTRACE_SETREGSET or PTRACE_GETREGSET request. (CVE-2012-1097,
Moderate)

Red Hat would like to thank H. Peter Anvin for reporting CVE-2012-1097.

This update also fixes several bugs and adds various enhancements.
Documentation for these changes will be available shortly from the
Technical Notes document linked to in the References section.

Users should upgrade to these updated packages, which contain backported
patches to correct these issues, and fix the bugs and add the enhancements
noted in the Technical Notes. The system must be rebooted for this update
to take effect.

Affected Software/OS:
kernel on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
