========================================================================== Ubuntu Security Notice USN-2049-1 December 07, 2013
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
Miroslav Vadkerti discovered a flaw in how the permissions for network sysctls are handled in the Linux kernel. An unprivileged local user could exploit this flaw to have privileged access to files in /proc/sys/net/. (CVE-2013-4270)
A flaw was discovered in the Linux kernel's dm snapshot facility. A remote authenticated user could exploit this flaw to obtain sensitive information or modify/corrupt data. (CVE-2013-4299)
Wannes Rombouts reported a vulnerability in the networking tuntap interface of the Linux kernel. A local user with the CAP_NET_ADMIN capability could leverage this flaw to gain full admin privileges. (CVE-2013-4343)
Alan Chester reported a flaw in the IPv6 Stream Control Transmission Protocol (SCTP) of the Linux kernel. A remote attacker could exploit this flaw to obtain sensitive information by sniffing network traffic. (CVE-2013-4350)
Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP Fragmentation Offload (UFO) processing. A remote attacker could leverage this flaw to cause a denial of service (system crash). (CVE-2013-4387)
Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP Fragmenttation Offload (UFO). An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2013-4470)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.10: linux-image-3.11.0-14-generic 3.11.0-14.21 linux-image-3.11.0-14-generic-lpae 3.11.0-14.21
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.
