USN-1183-1: Linux kernel vulnerabilities

Releases

• Ubuntu 10.10

Packages

• linux - Linux kernel

Details

Dan Rosenberg discovered that multiple terminal ioctls did not correctly
initialize structure memory. A local attacker could exploit this to read
portions of kernel stack memory, leading to a loss of privacy.
(CVE-2010-4076, CVE-2010-4077)

Neil Horman discovered that NFSv4 did not correctly handle certain orders
of operation with ACL data. A remote attacker with access to an NFSv4 mount
could exploit this to crash the system, leading to a denial of service.
(CVE-2011-1090)

Timo Warns discovered that OSF partition parsing routines did not correctly
clear memory. A local attacker with physical access could plug in a
specially crafted block device to read kernel memory, leading to a loss of
privacy. (CVE-2011-1163)

Timo Warns discovered that the GUID partition parsing routines did not
correctly validate certain structures. A local attacker with physical
access could plug in a specially crafted block device to crash the system,
leading to a denial of service. (CVE-2011-1577)

Oliver Hartkopp and Dave Jones discovered that the CAN network driver did
not correctly validate certain socket structures. If this driver was
loaded, a local attacker could crash the system, leading to a denial of
service. (CVE-2011-1598)

Vasiliy Kulikov discovered that the AGP driver did not check the size of
certain memory allocations. A local attacker with access to the video
subsystem could exploit this to run the system out of memory, leading to a
denial of service. (CVE-2011-1746)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.10

• linux-image-2.6.35-30-powerpc-smp - 2.6.35-30.56
• linux-image-2.6.35-30-versatile - 2.6.35-30.56
• linux-image-2.6.35-30-server - 2.6.35-30.56
• linux-image-2.6.35-30-powerpc64-smp - 2.6.35-30.56
• linux-image-2.6.35-30-virtual - 2.6.35-30.56
• linux-image-2.6.35-30-generic-pae - 2.6.35-30.56
• linux-image-2.6.35-30-omap - 2.6.35-30.56
• linux-image-2.6.35-30-generic - 2.6.35-30.56
• linux-image-2.6.35-30-powerpc - 2.6.35-30.56

After a standard system update you need to reboot your computer to make
all the necessary changes.
