SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionBenjamin Randazzo discovered an information leak in the md (multiple device) driver when the bitmap_info.file is disabled. A local privileged attacker could use this to obtain sensitive information from the kernel. (CVE-2015-5697)
Marc-Andre Lureau discovered that the vhost driver did not properly release the userspace provided log file descriptor. A privileged attacker could use this to cause a denial of service (resource exhaustion). (CVE-2015-6252).
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-3.19-generic, linux-image-3.19-generic-lpae and / or linux-image-3.19-lowlatency packages.
