Ubuntu alert USN-1183-1 (kernel)
========================================================================== Ubuntu Security Notice USN-1183-1 August 03, 2011 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.10 Summary: Multiple kernel flaws have been fixed. Software Description: - 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-generic 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-powerpc 2.6.35-30.56 linux-image-2.6.35-30-powerpc-smp 2.6.35-30.56 linux-image-2.6.35-30-powerpc64-smp 2.6.35-30.56 linux-image-2.6.35-30-server 2.6.35-30.56 linux-image-2.6.35-30-versatile 2.6.35-30.56 linux-image-2.6.35-30-virtual 2.6.35-30.56 After a standard system update you need to reboot your computer to make all the necessary changes.
