[Anders Kaseorg]

Synopsis: FEDORA-2011-15241 can now be patched using Ksplice
CVEs: CVE-2011-2699 CVE-2011-4077 CVE-2011-4081

Systems running Fedora 14 can now use Ksplice to patch against the 
latest Fedora security update, FEDORA-2011-15241.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 14 install 
these updates.  You can install these updates by running:

# /usr/sbin/uptrack-upgrade -y

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf, 
these updates will be installed automatically and you do not need to 
take any additional action.


DESCRIPTION

* CVE-2011-4077: Buffer overflow in xfs_readlink.

A flaw in the way the XFS filesystem implementation handled links with 
pathnames larger than MAXPATHLEN allowed an attacker to mount a 
malicious XFS image that could crash the system or result in privilege 
escalation.


* Improved fix for CVE-2011-2699.

Fedora's original fix for CVE-2011-2699 introduced a NULL dereference in 
udp6_ufo_fragment.


* CVE-2011-4081: NULL pointer dereference in GHASH cryptographic algorithm.

Nick Bowler reported an issue in the GHASH message digest algorithm. 
ghash_update can pass a NULL pointer to gf128mul_4k_lle in some cases, 
leading to a NULL pointer dereference (kernel OOPS).
