"The openSUSE 11.0 kernel was updated to 2.6.25.16.

It fixes various stability bugs and also security bugs.

CVE-2008-1673: Fixed the range checking in the ASN.1 decoder in NAT
for SNMP and CIFS, which could have been used by a remote attacker to
crash the machine.

CVE-2008-3276: An integer overflow flaw was found in the Linux kernel
dccp_setsockopt_change() function. An attacker may leverage this
vulnerability to trigger a kernel panic on a victim's machine
remotely.

CVE-2008-3272: The snd_seq_oss_synth_make_info function in
sound/core/seq/oss/seq_oss_synth.c in the sound subsystem does not
verify that the device number is within the range defined by
max_synthdev before returning certain data to the caller, which allows
local users to obtain sensitive information.

CVE-2008-3275: The (1) real_lookup and (2) __lookup_hash functions in
fs/namei.c in the vfs implementation do not prevent creation of a
child dentry for a deleted (aka S_DEAD) directory, which allows local
users to cause a denial of service ('overflow' of the UBIFS orphan
area) via a series of attempted file creations within deleted
directories.

Also lots of bugs were fixed."
