USN-1530-1 : linux-ti-omap4 vulnerabilities

Ubuntu Security Notice (C) 2012 Canonical, Inc. / NASL script (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

Andy Adamson discovered a flaw in the Linux kernel's NFSv4
implementation. A remote NFS server (attacker) could exploit this
flaw to cause a denial of service. (CVE-2011-4131)

Steve Grubb reported a flaw with Linux fscaps (file system base
capabilities) when used to increase the permissions of a process. For
application on which fscaps are in use a local attacker can disable
address space randomization to make attacking the process with raised
privileges easier. (CVE-2012-2123)

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface
(which is not available to unprivileged users until granted by a root
user) could exploit this flaw to crash the system or potential gain
administrative privileges. (CVE-2012-2136)

Stephan Mueller reported a flaw in the Linux kernel's dl2k network
driver's handling of ioctls. An unprivileged local user could
leverage this flaw to cause a denial of service. (CVE-2012-2313)

Timo Warns reported multiple flaws in the Linux kernel's hfsplus
filesystem. An unprivileged local user could exploit these flaws to
gain root system priviliges. (CVE-2012-2319)

A flaw was found in the Linux kernel's Reliable Datagram Sockets
(RDS) protocol implementation. A local, unprivileged user could use
this flaw to cause a denial of service. (CVE-2012-2372)

A flaw was discovered in the Linux kernel's NFSv4 (Network file
system) handling of ACLs (access control lists). A remote NFS server
(attacker) could cause a denial of service (OOPS). (CVE-2012-2375)
