High Nessus Plugin ID 86465
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that virtio networking in the Linux kernel did not handle fragments correctly, leading to kernel memory corruption. A remote attacker could use this to cause a denial of service (system crash) or possibly execute code with administrative privileges.
It was discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel did not verify sockets were properly bound before attempting to send a message, which could cause a NULL pointer dereference. An attacker could use this to cause a denial of service (system crash). (CVE-2015-6937).
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 packages.
