"This patch updates the SUSE Linux Enterprise 10 SP1 kernel. It fixes
various bugs and security issues.

The following security issues are addressed :

  - fs/open.c in the Linux kernel before 2.6.22 does not
    properly strip setuid and setgid bits when there is a
    write to a file, which allows local users to gain the
    privileges of a different group, and obtain sensitive
    information or possibly have unspecified other impact,
    by creating an executable file in a setgid directory
    through the (1) truncate or (2) ftruncate function in
    conjunction with memory-mapped I/O. (CVE-2008-4210)

  - The ext[234] filesystem code fails to properly handle
    corrupted data structures. With a mounted filesystem
    image or partition that have corrupted dir->i_size and
    dir->i_blocks, a user performing either a read or write
    operation on the mounted image or partition can lead to
    a possible denial of service by spamming the logfile.
    (CVE-2008-3528)

  - fs/direct-io.c in the dio subsystem in the Linux kernel
    did not properly zero out the dio struct, which allows
    local users to cause a denial of service (OOPS), as
    demonstrated by a certain fio test. (CVE-2007-6716)

All other bugfixes can be found by looking at the RPM changelog."
