Ubuntu 12.04 LTS : linux-lts-saucy vulnerabilities (USN-2070-1)

high Nessus Plugin ID 71796

Language:

Synopsis

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

Description

Vasily Kulikov reported a flaw in the Linux kernel's implementation of ptrace. An unprivileged local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-2929)

Dave Jones and Vince Weaver reported a flaw in the Linux kernel's per event subsystem that allows normal users to enable function tracing.
An unprivileged local user could exploit this flaw to obtain potentially sensitive information from the kernel. (CVE-2013-2930)

Stephan Mueller reported an error in the Linux kernel's ansi cprng random number generator. This flaw makes it easier for a local attacker to break cryptographic protections. (CVE-2013-4345)

Jason Wang discovered a bug in the network flow dissector in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (infinite loop). (CVE-2013-4348)

Multiple integer overflow flaws were discovered in the Alchemy LCD frame- buffer drivers in the Linux kernel. An unprivileged local user could exploit this flaw to gain administrative privileges.
(CVE-2013-4511)

Nico Golde and Fabian Yamaguchi reported a buffer overflow in the Ozmo Devices USB over WiFi devices. A local user could exploit this flaw to cause a denial of service or possibly unspecified impact.
(CVE-2013-4513)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's driver for Agere Systems HERMES II Wireless PC Cards. A local user with the CAP_NET_ADMIN capability could exploit this flaw to cause a denial of service or possibly gain administrative priviliges.
(CVE-2013-4514)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's driver for Beceem WIMAX chipset based devices. An unprivileged local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-4515)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's driver for the SystemBase Multi-2/PCI serial card. An unprivileged user could obtain sensitive information from kernel memory.
(CVE-2013-4516)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's debugfs filesystem. An administrative local user could exploit this flaw to cause a denial of service (OOPS). (CVE-2013-6378)

Nico Golde and Fabian Yamaguchi reported a flaw in the driver for Adaptec AACRAID scsi raid devices in the Linux kernel. A local user could use this flaw to cause a denial of service or possibly other unspecified impact. (CVE-2013-6380)

A flaw was discovered in the Linux kernel's compat ioctls for Adaptec AACRAID scsi raid devices. An unprivileged local user could send administrative commands to these devices potentially compromising the data stored on the device. (CVE-2013-6383)

Nico Golde reported a flaw in the Linux kernel's userspace IO (uio) driver. A local user could exploit this flaw to cause a denial of service (memory corruption) or possibly gain privileges.
(CVE-2013-6763)

A race condition flaw was discovered in the Linux kernel's ipc shared memory implementation. A local user could exploit this flaw to cause a denial of service (system crash) or possibly have unspecied other impacts. (CVE-2013-7026).

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-3.11-generic and / or linux-image-3.11-generic-lpae packages.
