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

High Nessus Plugin ID 68945

Synopsis

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

Description

This update fixes the following security issues :

- A flaw was found in the tcp_read_sock() function in the Linux kernel's IPv4 TCP/IP protocol suite implementation in the way socket buffers (skb) were handled. A local, unprivileged user could trigger this issue via a call to splice(), leading to a denial of service.
(CVE-2013-2128, Moderate)

- Information leak flaws in the Linux kernel could allow a local, unprivileged user to leak kernel memory to user-space. (CVE-2012-6548, CVE-2013-2634, CVE-2013-2635, CVE-2013-3222, CVE-2013-3224, CVE-2013-3225, Low)

- An information leak was found in the Linux kernel's POSIX signals implementation. A local, unprivileged user could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2013-0914, Low)

- A format string flaw was found in the ext3_msg() function in the Linux kernel's ext3 file system implementation. A local user who is able to mount an ext3 file system could use this flaw to cause a denial of service or, potentially, escalate their privileges.
(CVE-2013-1848, Low)

- A format string flaw was found in the b43_do_request_fw() function in the Linux kernel's b43 driver implementation. A local user who is able to specify the 'fwpostfix' b43 module parameter could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-2852, Low)

- A NULL pointer dereference flaw was found in the Linux kernel's ftrace and function tracer implementations. A local user who has the CAP_SYS_ADMIN capability could use this flaw to cause a denial of service.
(CVE-2013-3301, Low)

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

Solution

Update the affected packages.
