========================================================================== Ubuntu Security Notice USN-1878-1 June 14, 2013
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
An information leak was discovered in the Linux kernel when inotify is used to monitor the /dev/ptmx device. A local user could exploit this flaw to discover keystroke timing and potentially discover sensitive information like password length. (CVE-2013-0160)
A flaw was discovered in the Linux kernel's perf events subsystem for Intel Sandy Bridge and Ivy Bridge processors. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-2146)
An information leak was discovered in the Linux kernel's crypto API. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3076)
An information leak was discovered in the Linux kernel's rcvmsg path for ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3222)
An information leak was discovered in the Linux kernel's recvmsg path for ax25 address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3223)
An information leak was discovered in the Linux kernel's recvmsg path for the bluetooth address family. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3224)
An information leak was discovered in the Linux kernel's bluetooth rfcomm protocol support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3225)
An information leak was discovered in the Linux kernel's CAIF protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3227)
An information leak was discovered in the Linux kernel's IRDA (infrared) support subsystem. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3228)
An information leak was discovered in the Linux kernel's s390 - z/VM support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3229)
An information leak was discovered in the Linux kernel's llc (Logical Link Layer 2) support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3231)
An information leak was discovered in the Linux kernel's receive message handling for the netrom address family. A local user could exploit this flaw to obtain sensitive information from the kernel's stack memory. (CVE-2013-3232)
An information leak was discovered in the Linux kernel's Rose X.25 protocol layer. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3234)
An information leak was discovered in the Linux kernel's TIPC (Transparent Inter Process Communication) protocol implementation. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory. (CVE-2013-3235)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.2.0-48-generic 3.2.0-48.74 linux-image-3.2.0-48-generic-pae 3.2.0-48.74 linux-image-3.2.0-48-highbank 3.2.0-48.74 linux-image-3.2.0-48-omap 3.2.0-48.74 linux-image-3.2.0-48-powerpc-smp 3.2.0-48.74 linux-image-3.2.0-48-powerpc64-smp 3.2.0-48.74 linux-image-3.2.0-48-virtual 3.2.0-48.74
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.
