openSUSE Security Update : kernel (kernel-1593)

High Nessus Plugin ID 42952

Synopsis

The remote openSUSE host is missing a security update.

Description

The openSUSE 11.1 Kernel was updated to 2.6.27.39 fixing various bugs and security issues.

Following security issues have been fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to cause a denial of service. (Due to mmap_min_addr protection enabled by default, code execution is not possible.)

CVE-2009-2910: On x86_64 systems a information leak of high register contents (upper 32bit) was fixed.

CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux kernel when the appletalk and ipddp modules are loaded but the ipddp'N' device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams.

CVE-2009-3621: net/unix/af_unix.c in the Linux kernel allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket.

CVE-2009-3612 / CVE-2005-4881: The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue existed because of an incomplete fix for CVE-2005-4881.

CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls.

CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.

CVE-2009-3286: Sv4 in the Linux kernel does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.

Solution

Update the affected kernel packages.
