USN-1530-1: Linux kernel (OMAP4) vulnerabilities
10 August 2012
Several security issues were fixed in the kernel.
Releases
Packages
- linux-ti-omap4 - Linux kernel for OMAP4
Details
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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.04
After a standard system update you need to reboot your computer to make
all the necessary changes.
