New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 4.4


The remote Ubuntu host is missing one or more security-related patches.


A denial of service flaw was discovered in the Btrfs file system in the Linux kernel. A local user could cause a denial of service by creating a large number of files with names that have the same CRC32 hash value. (CVE-2012-5374)

A denial of service flaw was discovered in the Btrfs file system in the Linux kernel. A local user could cause a denial of service (prevent file creation) for a victim, by creating a file with a specific CRC32C hash value in a directory important to the victim.

Dan Carpenter discovered an information leak in the HP Smart Aray and Compaq SMART2 disk-array driver in the Linux kernel. A local user could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2013-2147).

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.
