security advisoryinformation leakDoSUbuntu 11.04 USN-1319-1 Critical: OMAP4 Kernel Threats Identified
Several security issues were fixed in the kernel.. =========================================================================Ubuntu Security Notice USN-1319-1 January 05, 2012 linux-ti-omap4 vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.04 Summary: Several security issues were fixed in the kernel. Software Description: - linux-ti-omap4: Linux kernel for OMAP4 Details: Peter Huewe discovered an information leak in the handling of reading security-related TPM data. A local, unprivileged user could read the results of a previous TPM command. (CVE-2011-1162) Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. (CVE-2011-2203) Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user who can mount a FUSE file system could cause a denial of service. (CVE-2011-3353) A flaw was found in how the Linux kernel handles user-defined key types. An unprivileged local user could exploit this to crash the system. (CVE-2011-4110) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.04: linux-image-2.6.38-1209-omap4 2.6.38-1209.20 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
