This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --===============5715780378006146357== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="------------enigF0784605BE58FEAF5A830442" This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigF0784605BE58FEAF5A830442 Content-Type: text/plain; charset=UTF- Content-Transfer-Encoding: quoted-printable ========================================================================== Ubuntu Security Notice USN-1935-1 August 20, 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: Chanam Park reported a Null pointer flaw in the Linux kernel's Ceph client. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1059) An information leak was discovered in the Linux kernel's fanotify interface. A local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-2148) Jonathan Salwan discovered an information leak in the Linux kernel's cdrom driver. A local user can exploit this leak to obtain sensitive information from kernel memory if the CD-ROM drive is malfunctioning. (CVE-2013-2164) Kees Cook discovered a format string vulnerability in the Linux kernel's disk block layer. A local user with administrator privileges could exploit this flaw to gain kernel privileges. (CVE-2013-2851) Hannes Frederic Sowa discovered that the Linux kernel's IPv6 stack does not correctly handle Router Advertisement (RA) message in some cases. A remote attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2013-4125) A vulnerability was discovered in the Linux kernel's vhost net driver. A local user could cause a denial of service (system crash) by powering on a virtual machine. (CVE-2013-4127) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.04: linux-image-3.8.0-29-generic 3.8.0-29.42 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.
