openSUSE Security Update : kernel (openSUSE-SU-2010:0397-1)

This script is Copyright (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.48 fixing
various bugs and security issues.

CVE-2010-1641: The do_gfs2_set_flags function in fs/gfs2/file.c in the
Linux kernel does not verify the ownership of a file, which allows
local users to bypass intended access restrictions via a SETFLAGS
ioctl request.

CVE-2010-1087: The nfs_wait_on_request function in fs/nfs/pagelist.c
in the Linux kernel allows attackers to cause a denial of service
(Oops) via unknown vectors related to truncating a file and an
operation that is not interruptible.

CVE-2010-1643: mm/shmem.c in the Linux kernel, when strict overcommit
is enabled, does not properly handle the export of shmemfs objects by
knfsd, which allows attackers to cause a denial of service (NULL
pointer dereference and knfsd crash) or possibly have unspecified
other impact via unknown vectors.

CVE-2010-1437: Race condition in the find_keyring_by_name function in
security/keys/keyring.c in the Linux kernel allows local users to
cause a denial of service (memory corruption and system crash) or
possibly have unspecified other impact via keyctl session commands
that trigger access to a dead keyring that is undergoing deletion by
the key_cleanup function.

CVE-2010-1446: arch/powerpc/mm/fsl_booke_mmu.c in KGDB in the Linux
kernel, when running on PowerPC, does not properly perform a security
check for access to a kernel page, which allows local users to
overwrite arbitrary kernel memory, related to Fsl booke.

CVE-2010-1162: The release_one_tty function in drivers/char/tty_io.c
in the Linux kernel omits certain required calls to the put_pid
function, which has unspecified impact and local attack vectors.

CVE-2009-4537: drivers/net/r8169.c in the r8169 driver in the Linux
kernel does not properly check the size of an Ethernet frame that
exceeds the MTU, which allows remote attackers to (1) cause a denial
of service (temporary network outage) via a packet with a crafted
size, in conjunction with certain packets containing A characters and
certain packets containing E characters; or (2) cause a denial of
service (system crash) via a packet with a crafted size, in
conjunction with certain packets containing '\0' characters, related
to the value of the status register and erroneous behavior associated
with the RxMaxSize register. NOTE: this vulnerability exists because
of an incorrect fix for CVE-2009-1389.
