This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --===============2546573949402284641== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="------------enigA13E829CFA90B71BF713D967" This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigA13E829CFA90B71BF713D967 Content-Type: text/plain; charset=UTF- Content-Transfer-Encoding: quoted-printable ========================================================================== Ubuntu Security Notice USN-1974-1 September 27, 2013 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 13.04 Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: Vince Weaver discovered a flaw in the perf subsystem of the Linux kernel on ARM platforms. A local user could exploit this flaw to gain privileges or cause a denial of service (system crash). (CVE-2013-4254) A memory leak was discovered in the user namespace facility of the Linux kernel. A local user could cause a denial of service (memory consumption) via the CLONE_NEWUSER unshare call. (CVE-2013-4205) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.04: linux-image-3.8.0-31-generic 3.8.0-31.46 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.
