This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --===============5641382225306398835== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="brXKBBPso17nMpagBVMo69SJ9jNiLMSiU" This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --brXKBBPso17nMpagBVMo69SJ9jNiLMSiU Content-Type: text/plain; charset=utf- Content-Transfer-Encoding: quoted-printable ========================================================================== Ubuntu Security Notice USN-2546-1 March 24, 2015 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.10 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: A flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2013-7421) A flaw was discovered in the crypto subsystem when screening module names for automatic module loading if the name contained a valid crypto module name, eg. vfat(aes). A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2014-9644) Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP (Stream Control Transmission Protocol) subsystem during INIT collisions. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges on the system. (CVE-2015-1421) Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets to too many different dsts/too fast. A remote attacker can exploit this flaw to cause a denial of service (system crash). (CVE-2015-1465) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.10: linux-image-3.16.0-33-generic 3.16.0-33.44 linux-image-3.16.0-33-generic-lpae 3.16.0-33.44 linux-image-3.16.0-33-lowlatency 3.16.0-33.44 linux-image-3.16.0-33-powerpc-e500mc 3.16.0-33.44 linux-image-3.16.0-33-powerpc-smp 3.16.0-33.44 linux-image-3.16.0-33-powerpc64-emb 3.16.0-33.44 linux-image-3.16.0-33-powerpc64-smp 3.16.0-33.44 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.
