========================================================================== Ubuntu Security Notice USN-1133-1 May 24, 2011 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 8.04 LTS Summary: Multiple flaws in the Linux kernel. Software Description: - linux: Linux kernel Details: Nelson Elhage discovered that Econet did not correctly handle AUN packets over UDP. A local attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2010-4342) Dan Rosenberg discovered that the OSS subsystem did not handle name termination correctly. A local attacker could exploit this crash the system or gain root privileges. (CVE-2010-4527) Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. On non-x86 systems, a local attacker could exploit this to read kernel heap memory, leading to a loss of privacy. (CVE-2010-4529) Dan Carpenter discovered that the TTPCI DVB driver did not check certain values during an ioctl. If the dvb-ttpci module was loaded, a local attacker could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges. (CVE-2011-0521) Dan Rosenberg discovered that XFS did not correctly initialize memory. A local attacker could make crafted ioctl calls to leak portions of kernel stack memory, leading to a loss of privacy. (CVE-2011-0711) 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 2.6.24-29.89 linux-image-2.6.24-29-generic 2.6.24-29.89 linux-image-2.6.24-29-hppa32 2.6.24-29.89 linux-image-2.6.24-29-hppa64 2.6.24-29.89 linux-image-2.6.24-29-itanium 2.6.24-29.89 linux-image-2.6.24-29-lpia 2.6.24-29.89 linux-image-2.6.24-29-lpiacompat 2.6.24-29.89 linux-image-2.6.24-29-mckinley 2.6.24-29.89 linux-image-2.6.24-29-openvz 2.6.24-29.89 linux-image-2.6.24-29-powerpc 2.6.24-29.89 linux-image-2.6.24-29-powerpc-smp 2.6.24-29.89 linux-image-2.6.24-29-powerpc64-smp 2.6.24-29.89 linux-image-2.6.24-29-rt 2.6.24-29.89 linux-image-2.6.24-29-server 2.6.24-29.89 linux-image-2.6.24-29-sparc64 2.6.24-29.89 linux-image-2.6.24-29-sparc64-smp 2.6.24-29.89 linux-image-2.6.24-29-virtual 2.6.24-29.89 linux-image-2.6.24-29-xen 2.6.24-29.89 After a standard system update you need to reboot your computer to make all the necessary changes.
