High Nessus Plugin ID 96444
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionAndrey Konovalov discovered that the ipv6 icmp implementation in the Linux kernel did not properly check data structures on send. A remote attacker could use this to cause a denial of service (system crash).
Andrey Konovalov discovered that signed integer overflows existed in the setsockopt() system call when handling the SO_SNDBUFFORCE and SO_RCVBUFFORCE options. A local attacker with the CAP_NET_ADMIN capability could use this to cause a denial of service (system crash or memory corruption). (CVE-2016-9793).
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-4.8-raspi2 and / or linux-image-raspi2 packages.
