========================================================================== Ubuntu Security Notice USN-2908-4 February 26, 2016
linux regression ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10
Summary:
USN-2908-1 introduced a regression in the Linux kernel.
Software Description: - linux: Linux kernel
Details:
USN-2908-1 fixed vulnerabilities in the Linux kernel for Ubuntu 15.10. An incorrect locking fix caused a regression that broke graphics displays for Ubuntu 15.10 guests running within VMWare virtual machines. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
halfdog discovered that OverlayFS, when mounting on top of a FUSE mount, incorrectly propagated file attributes, including setuid. A local unprivileged attacker could use this to gain privileges. (CVE-2016-1576) halfdog discovered that OverlayFS in the Linux kernel incorrectly propagated security sensitive extended attributes, such as POSIX ACLs. A local unprivileged attacker could use this to gain privileges. (CVE-2016-1575) It was discovered that the Linux kernel did not properly enforce rlimits for file descriptors sent over UNIX domain sockets. A local attacker could use this to cause a denial of service. (CVE-2013-4312) It was discovered that the Linux kernel's Filesystem in Userspace (FUSE) implementation did not handle initial zero length segments properly. A local attacker could use this to cause a denial of service (unkillable task). (CVE-2015-8785) Andy Lutomirski discovered a race condition in the Linux kernel's translation lookaside buffer (TLB) handling of flush events. A local attacker could use this to cause a denial of service or possibly leak sensitive information. (CVE-2016-2069)
