--===============6578693381757068556== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="2oox5VnwalALFvA7" Content-Disposition: inline --2oox5VnwalALFvA7 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-2797-1 November 05, 2015 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 Details: It was discovered that the Linux kernel did not check if a new IPv6 MTU set by a user space application was valid. A remote attacker could forge a route advertisement with an invalid MTU that a user space daemon like NetworkManager would honor and apply to the kernel, causing a denial of service. (CVE-2015-0272) It was discovered that in certain situations, a directory could be renamed outside of a bind mounted location. An attacker could use this to escape bind mount containment and gain access to sensitive information. (CVE-2015-2925) Moein Ghasemzadeh discovered that the USB WhiteHEAT serial driver contained hardcoded attributes about the USB devices. An attacker could construct a fake WhiteHEAT USB device that, when inserted, causes a denial of service (system crash). (CVE-2015-5257) It was discovered that the SCTP protocol implementation in the Linux kernel performed an incorrect sequence of protocol-initialization steps. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-5283) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-3.16.0-52-generic 3.16.0-52.71~14.04.1 linux-image-3.16.0-52-generic-lpae 3.16.0-52.71~14.04.1 linux-image-3.16.0-52-lowlatency 3.16.0-52.71~14.04.1 linux-image-3.16.0-52-powerpc-e500mc 3.16.0-52.71~14.04.1 linux-image-3.16.0-52-powerpc-smp 3.16.0-52.71~14.04.1 linux-image-3.16.0-52-powerpc64-emb 3.16.0-52.71~14.04.1 linux-image-3.16.0-52-powerpc64-smp 3.16.0-52.71~14.04.1 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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
