========================================================================== Ubuntu Security Notice USN-1939-1 September 06, 2013
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
Vasily Kulikov discovered a flaw in the Linux Kernel's perf tool that allows for privilege escalation. A local user could exploit this flaw to run commands as root when using the perf tool. (CVE-2013-1060)
Michael S. Tsirkin discovered a flaw in how the Linux kernel's KVM subsystem allocates memory slots for the guest's address space. A local user could exploit this flaw to gain system privileges or obtain sensitive information from kernel memory. (CVE-2013-1943)
A flaw was discovered in the SCTP (stream control transfer protocol) network protocol's handling of duplicate cookies in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (system crash) on another remote user querying the SCTP connection. (CVE-2013-2206)
Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the Linux kernel's IPv6 stack. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-4162)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 10.04 LTS: linux-image-2.6.32-51-386 2.6.32-51.113 linux-image-2.6.32-51-generic 2.6.32-51.113 linux-image-2.6.32-51-generic-pae 2.6.32-51.113 linux-image-2.6.32-51-ia64 2.6.32-51.113 linux-image-2.6.32-51-lpia 2.6.32-51.113 linux-image-2.6.32-51-powerpc 2.6.32-51.113 linux-image-2.6.32-51-powerpc-smp 2.6.32-51.113 linux-image-2.6.32-51-powerpc64-smp 2.6.32-51.113 linux-image-2.6.32-51-preempt 2.6.32-51.113 linux-image-2.6.32-51-server 2.6.32-51.113 linux-image-2.6.32-51-sparc64 2.6.32-51.113 linux-image-2.6.32-51-sparc64-smp 2.6.32-51.113 linux-image-2.6.32-51-versatile 2.6.32-51.113 linux-image-2.6.32-51-virtual 2.6.32-51.113
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.
