The remote host is missing updates to kernel-rt announced in
advisory RHSA-2009:1081.

These updated packages fix the following security issues:

  • a buffer overflow flaw was found in the CIFSTCon() function of the Linux
    kernel Common Internet File System (CIFS) implementation. When mounting a
    CIFS share, a malicious server could send an overly-long string to the
    client, possibly leading to a denial of service or privilege escalation on
    the client mounting the CIFS share. (CVE-2009-1439, Important)

  • the Linux kernel Network File System daemon (nfsd) implementation did not
    drop the CAP_MKNOD capability when handling requests from local,
    unprivileged users. This flaw could possibly lead to an information leak or
    privilege escalation. (CVE-2009-1072, Moderate)

  • a deficiency was found in the Linux kernel signals implementation. The
    kill_something_info() function did not check if a process was outside the
    caller’s namespace before sending the kill signal, making it possible to
    kill processes in all process ID (PID) namespaces, breaking PID namespace
    isolation. (CVE-2009-1338, Moderate)

  • a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and
    agp_generic_alloc_pages() functions did not zero out the memory pages they
    allocate, which may later be available to user-space processes. This flaw
    could possibly lead to an information leak. (CVE-2009-1192, Low)

All Red Hat Enterprise MRG users should upgrade to these updated packages,
which contain backported patches to resolve these issues. Note: The system
must be rebooted for this update to take effect.
