Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

This update fixes the following security issues :

- A divide-by-zero flaw was found in the
tcp_select_initial_window() function in the Linux
kernel's TCP/IP protocol suite implementation. A local,
unprivileged user could use this flaw to trigger a
denial of service by calling setsockopt() with certain
options. (CVE-2010-4165, Moderate)

- A use-after-free flaw in the mprotect() system call in
the Linux kernel could allow a local, unprivileged user
to cause a local denial of service. (CVE-2010-4169,
Moderate)

- A flaw was found in the Linux kernel execve() system
call implementation. A local, unprivileged user could
cause large amounts of memory to be allocated but not
visible to the OOM (Out of Memory) killer, triggering a
denial of service. (CVE-2010-4243, Moderate)

This update also fixes several bugs and adds two enhancements.

The system must be rebooted for this update to take effect.
