INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on Ubuntu 10.10
Maverick install these updates. You can install these updates by
# /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.
* 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).
* 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
* CVE-2011-4132: Denial of service in Journaling Block Device layer.
A flaw in the way the Journaling Block Device (JBD) layer handled an
invalid log first block value allowed an attacker to mount a malicious
ext3 or ext4 image that would crash the system.
* CVE-2011-4330: Buffer overflow in HFS file name translation logic.
Clement Lecigne reported a flaw in the way the HFS filesystem
implementation handled file names larger than HFS_NAMELEN. A missing
length check in hfs_mac2asc could result in a buffer overflow.
* CVE-2011-4326: Denial of service in IPv6 UDP Fragmentation Offload.
A flaw was found in the way the Linux kernel handled fragmented IPv6
UDP datagrams over the bridge with UDP Fragmentation Offload (UFO)
functionality on. A remote attacker could use this flaw to cause a
denial of service.
