USN-2967-1: Linux kernel vulnerabilities Ubuntu Security Notice USN-2967-1 9th May, 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 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 Aiptek Tablet USB device driver in theLinux kernel did not properly sanity check the endpoints reported by thedevice. An attacker with physical access could cause a denial of service(system crash). (CVE-2015-7515) Ralf Spenneberg discovered that the USB driver for Clie devices in theLinux kernel did not properly sanity check the endpoints reported by thedevice. An attacker with physical access could cause [ more… ]

USN-2968-1: Linux kernel vulnerabilities Ubuntu Security Notice USN-2968-1 9th May, 2016 linux 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 – Linux kernel Details Ralf Spenneberg discovered that the Aiptek Tablet USB device driver in theLinux kernel did not properly sanity check the endpoints reported by thedevice. An attacker with physical access could cause a denial of service(system crash). (CVE-2015-7515) Ben Hawkes discovered that the Linux kernel's AIO interface allowed singlewrites greater than 2GB, which could cause an integer overflow when writingto certain filesystems, socket or device types. A local attacker could thisto cause a denial of service (system crash) or possibly execute arbitrarycode. (CVE-2015-8830) It was discovered that the Linux kernel did not keep accurate track of pipebuffer details when [ more… ]
