The SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to and fixes various bugs and security issues.

Following security issues were fixed: CVE-2011-3191: A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host.

CVE-2011-3353: In the fuse filesystem, FUSE_NOTIFY_INVAL_ENTRY did not check the length of the write so the message processing could overrun and result in a BUG_ON() in fuse_copy_fill(). This flaw could be used by local users able to mount FUSE filesystems to crash the system.

CVE-2011-2928: The befs_follow_link function in fs/befs/linuxvfs.c in the Linux kernel did not validate the length attribute of long symlinks, which allowed local users to cause a denial of service (incorrect pointer dereference and OOPS) by accessing a long symlink on a malformed Be filesystem.
