The remote host is missing updates announced in
advisory RHSA-2009:0360.

The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.

These updated packages address the following security issues:

  • a memory leak exists in keyctl handling. A local, unprivileged user could
    use this flaw to deplete kernel memory, eventually leading to a denial of
    service. (CVE-2009-0031, Important)

  • an off-by-one underflow flaw was found in the eCryptfs subsystem. This
    could potentially cause a denial of service when the readlink() function
    returned an error. (CVE-2009-0269, Moderate)

  • a deficiency was found in the Remote BIOS Update (RBU) driver for Dell
    systems. This could allow a local, unprivileged user to cause a denial of
    service by reading zero bytes from the image_type or packet_size files in
    /sys/devices/platform/dell_rbu/. (CVE-2009-0322, Moderate)

  • an inverted logic flaw was found in the SysKonnect FDDI PCI adapter
    driver, allowing driver statistics to be reset only when the CAP_NET_ADMIN
    capability was absent (local, unprivileged users could reset driver
    statistics). (CVE-2009-0675, Moderate)

  • the sock_getsockopt() function in the Linux kernel did not properly
    initialize a data structure that can be directly returned to user-space
    when the getsockopt() function is called with SO_BSDCOMPAT optname set.
    This flaw could possibly lead to memory disclosure.
    (CVE-2009-0676, Moderate)

For other issues addressed in this update, please visit the referenced
advisories.

All Red Hat Enterprise MRG users should install this update which addresses
these vulnerabilities and fixes these bugs. For this update to take effect,
the system must be rebooted.
