========================================================================== Ubuntu Security Notice USN-1932-1 August 20, 2013 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.10 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: Chanam Park reported a Null pointer flaw in the Linux kernel's Ceph client. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1059) An information leak was discovered in the Linux kernel's fanotify interface. A local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-2148) Jonathan Salwan discovered an information leak in the Linux kernel's cdrom driver. A local user can exploit this leak to obtain sensitive information from kernel memory if the CD-ROM drive is malfunctioning. (CVE-2013-2164) Kees Cook discovered a format string vulnerability in the Linux kernel's disk block layer. A local user with administrator privileges could exploit this flaw to gain kernel privileges. (CVE-2013-2851) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.10: linux-image-3.5.0-39-generic 3.5.0-39.60 linux-image-3.5.0-39-highbank 3.5.0-39.60 linux-image-3.5.0-39-omap 3.5.0-39.60 linux-image-3.5.0-39-powerpc-smp 3.5.0-39.60 linux-image-3.5.0-39-powerpc64-smp 3.5.0-39.60 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.
