openSUSE Security Update : kernel (kernel-423)

Description

This update fixes various security issues and several bugs in the openSUSE 11.0 kernel. It was also updated to the stable version 2.6.25.20. CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call. CVE-2008-5700: libata did not set minimum timeouts for SG_IO requests, which allows local users to cause a denial of service (Programmed I/O mode on drives) via multiple simultaneous invocations of an unspecified test program. CVE-2008-5079: net/atm/svc.c in the ATM subsystem allowed local users to cause a denial of service (kernel infinite loop) by making two calls to svc_listen for the same socket, and then reading a /proc/net/atm/*vc file, related to corruption of the vcc table. CVE-2008-5300: Linux kernel 2.6.28 allows local users to cause a denial of service ('soft lockup' and process loss) via a large number of sendmsg function calls, which does not block during AF_UNIX garbage collection and triggers an OOM condition, a different vulnerability than CVE-2008-5029. CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors. CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function. CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec function in fs/hfs/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfs filesystem image with an invalid catalog namelength field, a related issue to CVE-2008-4933. CVE-2008-5182: The inotify functionality might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount. CVE-2008-3831: The i915 driver in drivers/char/drm/i915_dma.c does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration. CVE-2008-4554: The do_splice_from function in fs/splice.c did not reject file descriptors that have the O_APPEND flag set, which allows local users to bypass append mode and make arbitrary changes to other locations in the file.
