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: 5.9
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionA flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges.
A flaw was discovered in the crypto subsystem when screening module names for automatic module loading if the name contained a valid crypto module name, eg. vfat(aes). A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges.
Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP (Stream Control Transmission Protocol) subsystem during INIT collisions. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges on the system. (CVE-2015-1421)
Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets to too many different dsts/too fast. A remote attacker can exploit this flaw to cause a denial of service (system crash).
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-3.16-generic, linux-image-3.16-generic-lpae and / or linux-image-3.16-lowlatency packages.
