--===============5143253622958454877== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="d8Lz2Tf5e5STOWUP" Content-Disposition: inline --d8Lz2Tf5e5STOWUP Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-2908-1 February 22, 2016 linux 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: Linux kernel 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) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 15.10: linux-image-4.2.0-30-generic 4.2.0-30.35 linux-image-4.2.0-30-generic-lpae 4.2.0-30.35 linux-image-4.2.0-30-lowlatency 4.2.0-30.35 linux-image-4.2.0-30-powerpc-e500mc 4.2.0-30.35 linux-image-4.2.0-30-powerpc-smp 4.2.0-30.35 linux-image-4.2.0-30-powerpc64-emb 4.2.0-30.35 linux-image-4.2.0-30-powerpc64-smp 4.2.0-30.35 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
