========================================================================== Ubuntu Security Notice USN-1225-1 October 04, 2011 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 8.04 LTS Summary: Multiple kernel flaws have been fixed. Software Description: - linux: Linux kernel Details: Timo Warns discovered that the EFI GUID partition table was not correctly parsed. A physically local attacker that could insert mountable devices could exploit this to crash the system or possibly gain root privileges. (CVE-2011-1776) Dan Rosenberg discovered that the IPv4 diagnostic routines did not correctly validate certain requests. A local attacker could exploit this to consume CPU resources, leading to a denial of service. (CVE-2011-2213) Dan Rosenberg discovered that the Bluetooth stack incorrectly handled certain L2CAP requests. If a system was using Bluetooth, a remote attacker could send specially crafted traffic to crash the system or gain root privileges. (CVE-2011-2497) Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service. (CVE-2011-2699) Time Warns discovered that long symlinks were incorrectly handled on Be filesystems. A local attacker could exploit this with a malformed Be filesystem and crash the system, leading to a denial of service. (CVE-2011-2928) Darren Lavender discovered that the CIFS client incorrectly handled certain large values. A remote attacker with a malicious server could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2011-3191) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 8.04 LTS: linux-image-2.6.24-29-386 2.6.24-29.94 linux-image-2.6.24-29-generic 2.6.24-29.94 linux-image-2.6.24-29-hppa32 2.6.24-29.94 linux-image-2.6.24-29-hppa64 2.6.24-29.94 linux-image-2.6.24-29-itanium 2.6.24-29.94 linux-image-2.6.24-29-lpia 2.6.24-29.94 linux-image-2.6.24-29-lpiacompat 2.6.24-29.94 linux-image-2.6.24-29-mckinley 2.6.24-29.94 linux-image-2.6.24-29-openvz 2.6.24-29.94 linux-image-2.6.24-29-powerpc 2.6.24-29.94 linux-image-2.6.24-29-powerpc-smp 2.6.24-29.94 linux-image-2.6.24-29-powerpc64-smp 2.6.24-29.94 linux-image-2.6.24-29-rt 2.6.24-29.94 linux-image-2.6.24-29-server 2.6.24-29.94 linux-image-2.6.24-29-sparc64 2.6.24-29.94 linux-image-2.6.24-29-sparc64-smp 2.6.24-29.94 linux-image-2.6.24-29-virtual 2.6.24-29.94 linux-image-2.6.24-29-xen 2.6.24-29.94 After a standard system update you need to reboot your computer to make all the necessary changes.
