openSUSE 10 Security Update : kernel (kernel-6440)

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


Synopsis :

The remote openSUSE host is missing a security update.

Description :

This kernel update for openSUSE 10.3 fixes some bugs and several
security problems.

The following security issues are fixed: CVE-2009-2692: A missing NULL
pointer check in the socket sendpage function can be used by local
attackers to gain root privileges.

CVE-2009-2406: A kernel stack overflow when mounting eCryptfs
filesystems in parse_tag_11_packet() was fixed. Code execution might
be possible of ecryptfs is in use.

CVE-2009-2407: A kernel heap overflow when mounting eCryptfs
filesystems in parse_tag_3_packet() was fixed. Code execution might be
possible of ecryptfs is in use.

The compiler option -fno-delete-null-pointer-checks was added to the
kernel build, and the -fwrapv compiler option usage was fixed to be
used everywhere. This works around the compiler removing checks too
aggressively.

CVE-2009-1389: A crash in the r8169 driver when receiving large
packets was fixed. This is probably exploitable only in the local
network.

CVE-2009-0676: A memory disclosure via the SO_BSDCOMPAT socket option
was fixed.

CVE-2009-1630: The nfs_permission function in fs/nfs/dir.c in the NFS
client implementation when atomic_open is available, does not check
execute (aka EXEC or MAY_EXEC) permission bits, which allows local
users to bypass permissions and execute files, as demonstrated by
files on an NFSv4 fileserver.

random: make get_random_int() was made more random to enhance ASLR
protection.

Solution :

Update the affected kernel packages.

Risk factor :

High / CVSS Base Score : 7.8
