USN-2996-1: Linux kernel vulnerabilities Ubuntu Security Notice USN-2996-1 9th June, 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 Jann Horn discovered that eCryptfs improperly attempted to use the mmap()handler of a lower filesystem that did not implement one, causing arecursive page fault to occur. A local unprivileged attacker could use tocause a denial of service (system crash) or possibly execute arbitrary codewith administrative privileges. (CVE-2016-1583) Ralf Spenneberg discovered that the USB sound subsystem in the Linux kerneldid not properly validate USB device descriptors. An attacker with physicalaccess could use this to cause a denial of service (system crash).(CVE-2016-2184) Ralf Spenneberg discovered that the ATI Wonder Remote II USB driver in theLinux kernel did not properly [ more… ]

USN-3004-1: Linux kernel (Raspberry Pi 2) vulnerabilities Ubuntu Security Notice USN-3004-1 10th June, 2016 linux-raspi2 vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 15.10 Summary Several security issues were fixed in the kernel. Software description linux-raspi2 – Linux kernel for Raspberry Pi 2 Details Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linuxkernel incorrectly enables scatter/gather I/O. A remote attacker could usethis to obtain potentially sensitive information from kernel memory.(CVE-2016-2117) Jann Horn discovered that eCryptfs improperly attempted to use the mmap()handler of a lower filesystem that did not implement one, causing arecursive page fault to occur. A local unprivileged attacker could use tocause a denial of service (system crash) or possibly execute arbitrary codewith administrative privileges. (CVE-2016-1583) Jason A. Donenfeld discovered multiple out-of-bounds reads in the OZMO USBover wifi device drivers in [ more… ]
