SO: RHEL 5.x.
Type: Kernel
Importance: have security impact

How to Update:
# yum update
# reboot

You should check after upgrade if you have he new kernel version by typing:
# uname -mrs

Security fixes:
a) A missing capability check was found in the Linux kernel do_change_type routine. This could allow a local unprivileged user to gain privileged access or cause a denial of service. (CVE-2008-2931, Important)

b) A flaw was found in the Linux kernel Direct-IO implementation. This could allow a local unprivileged user to cause a denial of service. (CVE-2007-6716, Important)

c) Tobias Klein reported a missing check in the Linux kernel Open Sound System (OSS) implementation. This deficiency could lead to a possible information leak. (CVE-2008-3272, Moderate)

d) a deficiency was found in the Linux kernel virtual filesystem (VFS) implementation. This could allow a local unprivileged user to attempt file creation within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

e) A flaw was found in the Linux kernel tmpfs implementation. This could allow a local unprivileged user to read sensitive information from the kernel. (CVE-2007-6417, Moderate)

Bug fix
a) A kernel crash may have occurred on heavily-used Samba servers after 24 to 48 hours of use.

b) On certain systems, if multiple InfiniBand queue pairs simultaneously fell into an error state, an overrun may have occurred, stopping traffic.

c) With bridging, when forward delay was set to zero, setting an interface to the forwarding state was delayed by one or possibly two timers, depending on whether STP was enabled. This may have caused long delays in moving an interface to the forwarding state. This issue caused packet loss when migrating virtual machines, preventing them from being migrated without interrupting applications.
