========================================================================== Ubuntu Security Notice USN-1164-1 July 06, 2011 linux-fsl-imx51 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.04 LTS Summary: Multiple kernel flaws have been fixed. Software Description: - linux-fsl-imx51: Linux kernel for IMX51 Details: Thomas Pollet discovered that the RDS network protocol did not check certain iovec buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2010-3865) Dan Rosenberg discovered that the CAN protocol on 64bit systems did not correctly calculate the size of certain buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2010-3874) Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-3875) Vasiliy Kulikov discovered that the Linux kernel sockets implementation did not properly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-3876) Vasiliy Kulikov discovered that the TIPC interface did not correctly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-3877) Nelson Elhage discovered that the Linux kernel IPv4 implementation did not properly audit certain bytecodes in netlink messages. A local attacker could exploit this to cause the kernel to hang, leading to a denial of service. (CVE-2010-3880) Dan Rosenberg discovered that the RME Hammerfall DSP audio interface driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4080, CVE-2010-4081) Dan Rosenberg discovered that the VIA video driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4082) Dan Rosenberg discovered that the semctl syscall did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4083) James Bottomley discovered that the ICP vortex storage array controller driver did not validate certain sizes. A local attacker on a 64bit system could exploit this to crash the kernel, leading to a denial of service. (CVE-2010-4157) Dan Rosenberg discovered multiple flaws in the X.25 facilities parsing. If a system was using X.25, a remote attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-4164) It was discovered that multithreaded exec did not handle CPU timers correctly. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-4248) Nelson Elhage discovered that the kernel did not correctly handle process cleanup after triggering a recoverable kernel bug. If a local attacker were able to trigger certain kinds of kernel bugs, they could create a specially crafted process to gain root privileges. (CVE-2010-4258) 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) Tavis Ormandy discovered that the install_special_mapping function could bypass the mmap_min_addr restriction. A local attacker could exploit this to mmap 4096 bytes below the mmap_min_addr area, possibly improving the chances of performing NULL pointer dereference attacks. (CVE-2010-4346) 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 Rosenburg discovered that the CAN subsystem leaked kernel addresses into the /proc filesystem. A local attacker could use this to increase the chances of a successful memory corruption exploit. (CVE-2010-4565) Kees Cook discovered that some ethtool functions did not correctly clear heap memory. A local attacker with CAP_NET_ADMIN privileges could exploit this to read portions of kernel heap memory, leading to a loss of privacy. (CVE-2010-4655) Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. (CVE-2010-4656) Goldwyn Rodrigues discovered that the OCFS2 filesystem did not correctly clear memory when writing certain file holes. A local attacker could exploit this to read uninitialized data from the disk, leading to a loss of privacy. (CVE-2011-0463) 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) Jens Kuehnel discovered that the InfiniBand driver contained a race condition. On systems using InfiniBand, a local attacker could send specially crafted requests to crash the system, leading to a denial of service. (CVE-2011-0695) 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) Rafael Dominguez Vega discovered that the caiaq Native Instruments USB driver did not correctly validate string lengths. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. (CVE-2011-0712) Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. (CVE-2011-1017) Julien Tinnes discovered that the kernel did not correctly validate the signal structure from tkill(). A local attacker could exploit this to send signals to arbitrary threads, possibly bypassing expected restrictions. (CVE-2011-1182) Dan Rosenberg discovered that MPT devices did not correctly validate certain values in ioctl calls. If these drivers were loaded, a local attacker could exploit this to read arbitrary kernel memory, leading to a loss of privacy. (CVE-2011-1494, CVE-2011-1495) Tavis Ormandy discovered that the pidmap function did not correctly handle large requests. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-1593) Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl values. A local attacker with access to the video subsystem could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges. (CVE-2011-1745, CVE-2011-2022) 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, CVE-2011-1747) 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-2011-1748) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: linux-image-2.6.31-609-imx51 2.6.31-609.26 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.
