 Mandriva Linux Security Advisory                         MDKSA-2006:197
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : kernel
 Date    : November 3, 2006
 Affected: 2007.0
 _______________________________________________________________________
 
 Problem Description:
 
 Some vulnerabilities were discovered and corrected in the Linux 2.6
 kernel:

 Bugs in the netfilter for IPv6 code, as reported by Mark Dowd, were
 fixed (CVE-2006-4572).

 The ATM subsystem of the Linux kernel could allow a remote attacker to
 cause a Denial of Service (panic) via unknown vectors that cause the
 ATM subsystem to access the memory of socket buffers after they are
 freed (CVE-2006-4997).

 The provided packages are patched to fix these vulnerabilities.  All
 users are encouraged to upgrade to these updated kernels immediately
 and reboot to effect the fixes.

 In addition to these security fixes, other fixes have been included
 such as:

 - updated to 2.6.17.14 - fix wrong error handling in pccard_store_cis -
 add NX mask for PTE entry on x86_64 - fix snd-hda-intel OOPS -
 backported support r8169-related (r8168/r8169SC) network chipsets -
 explicitly initialize some members of the drm_driver structure,
 otherwise NULL init will have bad side effects (mach64) - support for
 building a nosrc.rpm package - fixed unplug/eject on pcmcia cards with
 r8169 chipsets - fix libata resource conflicts - fix xenU crash and
 re-enable domU boot logs - fix refcount error triggered by software
 using /proc/[pid]/auxv
