The remote host is missing updates announced in
advisory RHSA-2009:1635.
The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.
These updated packages fix the following security issues:
a NULL pointer dereference flaw was found in the NFSv4 implementation in
the Linux kernel. Several of the NFSv4 file locking functions failed to
check whether a file had been opened on the server before performing
locking operations on it. A local user on a system with an NFSv4 share
mounted could possibly use this flaw to cause a denial of service or
escalate their privileges. (CVE-2009-3726, Important)
permission issues were found in the megaraid_sas driver (for SAS based
RAID controllers) in the Linux kernel. The dbg_lvl and poll_mode_io
files on the sysfs file system (/sys/) had world-writable permissions.
This could allow local, unprivileged users to change the behavior of the
driver. (CVE-2009-3889, CVE-2009-3939, Moderate)
Users should upgrade to these updated packages, which contain backported
patches to correct these issues and add these enhancements. The system must
be rebooted for this update to take effect.
