Scientific Linux Security Update : kernel for SL 5.x on i386/x86_64

High Nessus Plugin ID 60634


The remote Scientific Linux host is missing one or more security updates.


CVE-2007-5966 kernel: non-root can trigger cpu_idle soft lockup CVE-2009-1385 kernel: e1000_clean_rx_irq() denial of service CVE-2009-1388 kernel: do_coredump() vs ptrace_start() deadlock CVE-2009-1389 kernel: r8169: fix crash when large packets are received CVE-2009-1895 kernel: personality: fix PER_CLEAR_ON_SETID CVE-2009-2406 kernel: ecryptfs stack overflow in parse_tag_11_packet() CVE-2009-2407 kernel: ecryptfs heap overflow in parse_tag_3_packet()

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 (kernel panic). (CVE-2007-5966, Important)

- 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. (CVE-2009-1385, Important)

- 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. (CVE-2009-1389, Important)

- 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 (ASLR) security feature.
(CVE-2009-1895, Important)

- 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. (CVE-2009-2406, CVE-2009-2407, Important)

- 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.
(CVE-2009-1388, Moderate)

Bug fixes :

- possible host (dom0) crash when installing a Xen para-virtualized guest while another para-virtualized guest was rebooting. (BZ#497812)

- no audit record for a directory removal if the directory and its subtree were recursively watched by an audit rule. (BZ#507561)

- 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. (BZ#506029)

- incorrect stylus button handling when moving it away then returning it to the tablet for Wacom Cintiq 21UX and Intuos tablets. (BZ#508275)

- 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 (this caused such programs to abort).

- write operations could be blocked even when using O_NONBLOCK. (BZ#510239)

- the 'pci=nomsi' option was required for installing and booting Red Hat Enterprise Linux 5.2 on systems with VIA VT3364 chipsets. (BZ#507529)

- shutting down, destroying, or migrating Xen guests with large amounts of memory could cause other guests to be temporarily unresponsive. (BZ#512311)
