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: 5.8
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionPaolo Bonzini discovered a flaw in Linux's handling of the SG_IO ioctl command. A local user, or user in a VM could exploit this flaw to bypass restrictions and gain read/write access to all data on the affected block device. (CVE-2011-4127)
A flaw was found in KVM's Programmable Interval Timer (PIT). When a virtual interrupt control is not available a local user could use this to cause a denial of service by starting a timer. (CVE-2011-4622)
A flaw was discovered in the XFS filesystem. If a local user mounts a specially crafted XFS image it could potential execute arbitrary code on the system. (CVE-2012-0038)
A flaw was found in the Linux kernel's ext4 file system when mounting a corrupt filesystem. A user-assisted remote attacker could exploit this flaw to cause a denial of service. (CVE-2012-2100).
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.
