SuSE 11 Security Update : Linux kernel (SAT Patch Numbers 1581 / 1588 / 1591)

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.

Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 11 Kernel was updated to fixing
various bugs and security issues.

The following security issues have been fixed :

- 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-2009-3547)

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

- 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-2009-2903)

- net/1/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-2009-3621)

- 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 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-2009-3612 / CVE-2005-4881)

- 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-2009-3620)

- 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.

- 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. (CVE-2009-3286)
