USN-1220-1 : linux-ti-omap4 vulnerabilities

Critical Nessus Plugin ID 56345

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.9

Synopsis

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

Description

Ryan Sweat discovered that the kernel incorrectly handled certain VLAN packets. On some systems, a remote attacker could send specially crafted traffic to crash the system, leading to a denial of service.
(CVE-2011-1576)

Timo Warns discovered that the EFI GUID partition table was not correctly parsed. A physically local attacker that could insert mountable devices could exploit this to crash the system or possibly gain root privileges. (CVE-2011-1776)

Dan Rosenberg discovered that the IPv4 diagnostic routines did not correctly validate certain requests. A local attacker could exploit this to consume CPU resources, leading to a denial of service.
(CVE-2011-2213)

Dan Rosenberg discovered that the Bluetooth stack incorrectly handled certain L2CAP requests. If a system was using Bluetooth, a remote attacker could send specially crafted traffic to crash the system or gain root privileges. (CVE-2011-2497)

Mauro Carvalho Chehab discovered that the si4713 radio driver did not correctly check the length of memory copies. If this hardware was available, a local attacker could exploit this to crash the system or gain root privileges. (CVE-2011-2700)

Herbert Xu discovered that certain fields were incorrectly handled when Generic Receive Offload (CVE-2011-2723)

Time Warns discovered that long symlinks were incorrectly handled on Be filesystems. A local attacker could exploit this with a malformed Be filesystem and crash the system, leading to a denial of service.
(CVE-2011-2928)

Dan Kaminsky discovered that the kernel incorrectly handled random sequence number generation. An attacker could use this flaw to possibly predict sequence numbers and inject packets. (CVE-2011-3188)

Darren Lavender discovered that the CIFS client incorrectly handled certain large values. A remote attacker with a malicious server could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2011-3191)

Solution

Update the affected package(s).
