medium Nessus Plugin ID 61185

Language:

Synopsis

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

Description

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

This update fixes the following security issues :

- The proc file system could allow a local, unprivileged user to obtain sensitive information or possibly cause integrity issues. (CVE-2011-1020, Moderate)

- Non-member VLAN (virtual LAN) packet handling for interfaces in promiscuous mode and also using the be2net driver could allow an attacker on the local network to cause a denial of service. (CVE-2011-3347, Moderate)

- A flaw was found in the Linux kernel in the way splitting two extents in ext4_ext_convert_to_initialized() worked. A local, unprivileged user with access to mount and unmount ext4 file systems could use this flaw to cause a denial of service. (CVE-2011-3638, Moderate)

- A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service.
(CVE-2011-4110, Moderate)

This update also fixes several hundred bugs and adds enhancements.
Refer to the upstream Release Notes for information on the most significant of these changes.

All Scientific Linux 6 users are advised to install these updated packages, which correct these issues, and fix the bugs and add the enhancements noted. The system must be rebooted for this update to take effect.
