========================================================================== Ubuntu Security Notice USN-3072-1 August 29, 2016 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: Kangjie Lu discovered an information leak in the Reliable Datagram Sockets (RDS) implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-5244) Yue Cao et al discovered a flaw in the TCP implementation's handling of challenge acks in the Linux kernel. A remote attacker could use this to cause a denial of service (reset connection) or inject content into an TCP stream. (CVE-2016-5696) It was discovered that a heap based buffer overflow existed in the USB HID driver in the Linux kernel. A local attacker could use this cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-5829) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.2.0-109-generic 3.2.0-109.150 linux-image-3.2.0-109-generic-pae 3.2.0-109.150 linux-image-3.2.0-109-highbank 3.2.0-109.150 linux-image-3.2.0-109-omap 3.2.0-109.150 linux-image-3.2.0-109-powerpc-smp 3.2.0-109.150 linux-image-3.2.0-109-powerpc64-smp 3.2.0-109.150 linux-image-3.2.0-109-virtual 3.2.0-109.150 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. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
