Scientific Linux Security Update : kernel on SL6.x i386/x86_64

Medium Nessus Plugin ID 60965

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.

Solution

Update the affected packages.
