CESA-2009:1193 -- centos 5 i386 kernel

Class: PATCHFamily: unix




The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * the possibility of a timeout value overflow was found in the Linux kernel high-resolution timers functionality, hrtimers. This could allow a local, unprivileged user to execute arbitrary code, or cause a denial of service . * a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially-crafted packet that would cause a denial of service or code execution. * Michael Tokarev reported a flaw in the Realtek r8169 Ethernet driver in the Linux kernel. This driver allowed interfaces using this driver to receive frames larger than could be handled, which could lead to a remote denial of service or code execution. * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization security feature. * Ramon de Carvalho Valle reported two flaws in the Linux kernel eCryptfs implementation. A local attacker with permissions to perform an eCryptfs mount could modify the metadata of the files in that eCrypfts mount to cause a buffer overflow, leading to a denial of service or privilege escalation. * Konstantin Khlebnikov discovered a race condition in the ptrace implementation in the Linux kernel. This race condition can occur when the process tracing and the process being traced participate in a core dump. A local, unprivileged user could use this flaw to trigger a deadlock, resulting in a partial denial of service. Bug fixes: * possible host crash when installing a Xen para-virtualized guest while another para-virtualized guest was rebooting. * no audit record for a directory removal if the directory and its subtree were recursively watched by an audit rule. * running "echo 1 > /proc/sys/vm/drop_caches" on systems under high memory load could cause a kernel panic. * on 32-bit systems, core dumps for some multithreaded applications did not include all thread information. * a stack buffer used by get_event_name was not large enough for the nul terminator sprintf writes. This could lead to an invalid pointer or kernel panic. * when using the aic94xx driver, a system with SATA drives may not boot due to a bug in libsas. * incorrect stylus button handling when moving it away then returning it to the tablet for Wacom Cintiq 21UX and Intuos tablets. * CPU "soft lockup" messages and possibly a system hang on systems with certain Broadcom network devices and running the Linux kernel from the kernel-xen package. * on 64-bit PowerPC, getitimer failed for programs using the ITIMER_REAL timer and that were also compiled for 64-bit systems . * write operations could be blocked even when using O_NONBLOCK. * the "pci=nomsi" option was required for installing and booting Red Hat Enterprise Linux 5.2 on systems with VIA VT3364 chipsets. * shutting down, destroying, or migrating Xen guests with large amounts of memory could cause other guests to be temporarily unresponsive. Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
