USN-3187-1: Linux kernel vulnerabilities Ubuntu Security Notice USN-3187-1 3rd February, 2017 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 Andrey Konovalov discovered that the SCTP implementation in the Linuxkernel improperly handled validation of incoming data. A remote attackercould use this to cause a denial of service (system crash). (CVE-2016-9555) It was discovered that multiple memory leaks existed in the XFSimplementation in the Linux kernel. A local attacker could use this tocause a denial of service (memory consumption). (CVE-2016-9685) Update instructions The problem can be corrected by updating your system to the following package version: Ubuntu 12.04 LTS: linux-image-3.2.0-121-powerpc-smp 3.2.0-121.164 linux-image-powerpc-smp 3.2.0.121.136 linux-image-3.2.0-121-highbank 3.2.0-121.164 linux-image-3.2.0-121-powerpc64-smp 3.2.0-121.164 linux-image-3.2.0-121-virtual 3.2.0-121.164 linux-image-3.2.0-121-generic 3.2.0-121.164 linux-image-3.2.0-121-generic-pae 3.2.0-121.164 linux-image-generic-pae 3.2.0.121.136 linux-image-highbank 3.2.0.121.136 linux-image-3.2.0-121-omap [ more… ]
