1) Problem Description and Brief Discussion
The openSUSE 10.3 kernel was updated to fix various security problems
and bugs. Following security bugs were fixed:
CVE-2008-5079: net/atm/svc.c in the ATM subsystem allowed local users to cause a denial of service (kernel infinite loop) by making two calls
to svc_listen for the same socket, and then reading a /proc/net/atm/*vc
file, related to corruption of the vcc table.
CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes
indirect recursive calls to itself through calls to the fput function,
which allows local users to cause a denial of service (panic) via
vectors related to sending an SCM_RIGHTS message through a UNIX domain
socket and closing file descriptors.
CVE-2008-5134: Buffer overflow in the lbs_process_bss function
in drivers/net/wireless/libertas/scan.c in the libertas subsystem
allowed remote attackers to have an unknown impact via an "invalid
beacon/probe response."
CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in
fs/hfsplus/catalog.c allowed attackers to cause a denial of service
(memory corruption or system crash) via an hfsplus filesystem
image with an invalid catalog namelength field, related to the
hfsplus_cat_build_key_uni function.
CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec
function in fs/hfs/catalog.c allowed attackers to cause a denial of
service (memory corruption or system crash) via an hfs filesystem
image with an invalid catalog namelength field, a related issue to
CVE-2008-4933.
CVE-2008-5182: The inotify functionality might allow local users to
gain privileges via unknown vectors related to race conditions in
inotify watch removal and umount.
2) Solution or Work-Around
There is no known workaround, please install the update packages.
3) Special Instructions and Notes
Please restart the machine after installing the update.
4) Package Location and Checksums
The preferred method for installing security updates is to use the YaST
Online Update (YOU) tool. YOU detects which updates are required and
automatically performs the necessary steps to verify and install them.
Alternatively, download the update packages for your distribution manually
and verify their integrity by the methods listed in Section 6 of this
announcement. Then install the packages using the command
rpm -Fhv
