Description

This SUSE Linux Enterprise 11 Service Pack 1 kernel contains various security fixes and other bugfixes.

Notable larger bug fixes and changes :

  • A deadlock in virtual interface handling in XEN introduced by the last update has been fixed.

  • The btrfs file system received backports of lots of fixes from 2.6.35.

  • An OCFS2 data corruption during high load has been fixed.

  • Custom truncation length has been added for authentication mechanisms in XFRM to enable IPv6 certification. The following security issues have been fixed :

  • Several buffer overflows in the Novell Client novfs kernel module could be abused by local users to execute code in kernel space.

  • On ext4 file systems, the MOVE_EXT ioctl() can overwrite append-only files. (CVE-2010-2066)

  • A NULL pointer de-reference in the l2tp protocol can cause an oops, which leads to a denial of service. (CVE-2010-2495)

  • Insufficient permission checking for the setflags ioctl() in the gfs2 filesystem. (CVE-2010-1641)
