========================================================================== Ubuntu Security Notice USN-1936-1 August 20, 2013
linux-lts-raring vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-lts-raring: Linux hardware enablement kernel from Raring
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)
Kees Cook discovered a format string vulnerability in the Broadcom B43 wireless driver for the Linux kernel. A local user could exploit this flaw to gain administrative privileges. (CVE-2013-2852)
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)
Marcus Moeller and Ken Fallon discovered that the CIFS incorrectly built certain paths. A local attacker with access to a CIFS partition could exploit this to crash the system, leading to a denial of service. (CVE-2013-4247)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.8.0-29-generic 3.8.0-29.42~precise1
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.
