SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionChanam 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.
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)
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).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected linux-image-3.8-generic package.
