USN-2929-2: Linux kernel (Trusty HWE) vulnerabilities Ubuntu Security Notice USN-2929-2 14th March, 2016 linux-lts-trusty 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-lts-trusty – Linux hardware enablement kernel from Trusty for Precise Details Ben Hawkes discovered that the Linux netfilter implementation did notcorrectly perform validation when handling IPT_SO_SET_REPLACE events. Alocal unprivileged attacker could use this to cause a denial of service(system crash) or possibly execute arbitrary code with administrativeprivileges. (CVE-2016-3134) It was discovered that the Linux kernel did not properly enforce rlimitsfor file descriptors sent over UNIX domain sockets. A local attacker coulduse this to cause a denial of service. (CVE-2013-4312) Ralf Spenneberg discovered that the USB driver for Clie devices in theLinux kernel did not properly sanity check the endpoints reported [ more… ]

USN-2931-1: Linux kernel (Utopic HWE) vulnerabilities Ubuntu Security Notice USN-2931-1 14th March, 2016 linux-lts-utopic vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 LTS Summary Several security issues were fixed in the kernel. Software description linux-lts-utopic – Linux hardware enablement kernel from Utopic for Trusty Details Ben Hawkes discovered that the Linux netfilter implementation did notcorrectly perform validation when handling IPT_SO_SET_REPLACE events. Alocal unprivileged attacker could use this to cause a denial of service(system crash) or possibly execute arbitrary code with administrativeprivileges. (CVE-2016-3134) It was discovered that the Linux kernel did not properly enforce rlimitsfor file descriptors sent over UNIX domain sockets. A local attacker coulduse this to cause a denial of service. (CVE-2013-4312) It was discovered that a race condition existed when handling heartbeat-timeout events in the SCTP implementation of the Linux kernel. A [ more… ]

USN-2930-2: Linux kernel (Wily HWE) vulnerabilities Ubuntu Security Notice USN-2930-2 14th March, 2016 linux-lts-wily vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 LTS Summary Several security issues were fixed in the kernel. Software description linux-lts-wily – Linux hardware enablement kernel from Wily for Trusty Details Ben Hawkes discovered that the Linux netfilter implementation did notcorrectly perform validation when handling IPT_SO_SET_REPLACE events. Alocal unprivileged attacker could use this to cause a denial of service(system crash) or possibly execute arbitrary code with administrativeprivileges. (CVE-2016-3134) Ben Hawkes discovered an integer overflow in the Linux netfilterimplementation. On systems running 32 bit kernels, a local unprivilegedattacker could use this to cause a denial of service (system crash) orpossibly execute arbitrary code with administrative privileges.(CVE-2016-3135) Ralf Spenneberg discovered that the USB driver for Clie devices in theLinux kernel did not [ more… ]

USN-2928-1: Linux kernel vulnerability Ubuntu Security Notice USN-2928-1 14th March, 2016 linux vulnerability A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.04 LTS Summary The system could be made to crash or run programs as an administrator by someone with physical access. Software description linux – Linux kernel Details Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectlyperformed a double-free. A local attacker with physical access could usethis to cause a denial of service (system crash) or possibly executearbitrary code with administrative privileges. Update instructions The problem can be corrected by updating your system to the following package version: Ubuntu 12.04 LTS: linux-image-3.2.0-101-omap 3.2.0-101.141 linux-image-3.2.0-101-powerpc64-smp 3.2.0-101.141 linux-image-3.2.0-101-highbank 3.2.0-101.141 linux-image-3.2.0-101-powerpc-smp 3.2.0-101.141 linux-image-3.2.0-101-generic 3.2.0-101.141 linux-image-3.2.0-101-virtual 3.2.0-101.141 linux-image-3.2.0-101-generic-pae 3.2.0-101.141 To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
