This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --===============2126676363965497435== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="vwUBQMsx6ghcrfSLpHrn6AIl1943xFxCL" This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --vwUBQMsx6ghcrfSLpHrn6AIl1943xFxCL Content-Type: text/plain; charset=utf- Content-Transfer-Encoding: quoted-printable ========================================================================== Ubuntu Security Notice USN-2466-1 January 13, 2015 linux 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: Linux kernel Details: A null pointer dereference flaw was discovered in the the Linux kernel's SCTP implementation when ASCONF is used. A remote attacker could exploit this flaw to cause a denial of service (system crash) via a malformed INIT chunk. (CVE-2014-7841) A race condition with MMIO and PIO transactions in the KVM (Kernel Virtual Machine) subsystem of the Linux kernel was discovered. A guest OS user could exploit this flaw to cause a denial of service (guest OS crash) via a specially crafted application. (CVE-2014-7842) MiloÅ¡ PrchlÃk reported a flaw in how the ARM64 platform handles a single byte overflow in __clear_user. A local user could exploit this flaw to cause a denial of service (system crash) by reading one byte beyond a /dev/zero page boundary. (CVE-2014-7843) A stack buffer overflow was discovered in the ioctl command handling for the Technotrend/Hauppauge USB DEC devices driver. A local user could exploit this flaw to cause a denial of service (system crash) or possibly gain privileges. (CVE-2014-8884) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-3.13.0-44-generic 3.13.0-44.73 linux-image-3.13.0-44-generic-lpae 3.13.0-44.73 linux-image-3.13.0-44-lowlatency 3.13.0-44.73 linux-image-3.13.0-44-powerpc-e500 3.13.0-44.73 linux-image-3.13.0-44-powerpc-e500mc 3.13.0-44.73 linux-image-3.13.0-44-powerpc-smp 3.13.0-44.73 linux-image-3.13.0-44-powerpc64-emb 3.13.0-44.73 linux-image-3.13.0-44-powerpc64-smp 3.13.0-44.73 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.
