Ubuntu 12.10 : linux vulnerabilities (USN-1881-1)

medium Nessus Plugin ID 66904

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

An information leak was discovered in the Linux kernel when inotify is used to monitor the /dev/ptmx device. A local user could exploit this flaw to discover keystroke timing and potentially discover sensitive information like password length. (CVE-2013-0160)

An information leak was discovered in the Linux kernel's tkill and tgkill system calls when used from compat processes. A local user could exploit this flaw to examine potentially sensitive kernel memory. (CVE-2013-2141)

A flaw was discovered in the Linux kernel's perf events subsystem for Intel Sandy Bridge and Ivy Bridge processors. A local user could exploit this flaw to cause a denial of service (system crash).
(CVE-2013-2146)

An information leak was discovered in the Linux kernel's crypto API. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3076)

An information leak was discovered in the Linux kernel's rcvmsg path for ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3222)

An information leak was discovered in the Linux kernel's recvmsg path for ax25 address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3223)

An information leak was discovered in the Linux kernel's recvmsg path for the bluetooth address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3224)

An information leak was discovered in the Linux kernel's bluetooth rfcomm protocol support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3225)

An information leak was discovered in the Linux kernel's CAIF protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3227)

An information leak was discovered in the Linux kernel's IRDA (infrared) support subsystem. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3228)

An information leak was discovered in the Linux kernel's s390 - z/VM support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3229)

An information leak was discovered in the Linux kernel's l2tp (Layer Two Tunneling Protocol) implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3230)

An information leak was discovered in the Linux kernel's llc (Logical Link Layer 2) support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3231)

An information leak was discovered in the Linux kernel's receive message handling for the netrom address family. A local user could exploit this flaw to obtain sensitive information from the kernel's stack memory. (CVE-2013-3232)

An information leak was discovered in the Linux kernel's nfc (near field communication) support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3233)

An information leak was discovered in the Linux kernel's Rose X.25 protocol layer. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3234)

An information leak was discovered in the Linux kernel's TIPC (Transparent Inter Process Communication) protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3235).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected linux-image-3.5-generic and / or linux-image-3.5-highbank packages.
