========================================================================== Ubuntu Security Notice USN-2071-1 January 03, 2014
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
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)
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 adminstrative 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)
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)
Evan Huus reported a buffer overflow in the Linux kernel's radiotap header parsing. A remote attacker could cause a denial of service (buffer over- read) via a specially crafted header. (CVE-2013-7027)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.10: linux-image-3.5.0-45-generic 3.5.0-45.68 linux-image-3.5.0-45-highbank 3.5.0-45.68 linux-image-3.5.0-45-omap 3.5.0-45.68 linux-image-3.5.0-45-powerpc-smp 3.5.0-45.68 linux-image-3.5.0-45-powerpc64-smp 3.5.0-45.68
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
