The remote host is missing updates to the kernel announced in
advisory RHSA-2009:1077.

This update includes backported fixes for two approved security issues.
These issues only affected users of Red Hat Enterprise Linux 4.7 Extended
Update Support, as they have already been addressed for users of Red Hat
Enterprise Linux 4 in the 4.8 update, RHSA-2009:1024.

  • the exit_notify() function in the Linux kernel did not properly reset the
    exit signal if a process executed a set user ID (setuid) application before
    exiting. This could allow a local, unprivileged user to elevate their
    privileges. (CVE-2009-1337, Important)

  • the Linux kernel implementation of the Network File System (NFS) version
    4 did not properly initialize the file name limit in the nfs_server data
    structure. This flaw could possibly lead to a denial of service on a client
    mounting an NFSv4 share. (CVE-2009-1336, Moderate)

Users should upgrade to these updated packages, which contain backported
patches to correct these issues. For this update to take effect, the system
must be rebooted.
