USN-3445-1: Linux kernel vulnerabilities
First published: Tue Oct 10 2017(Updated: )
Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation in the Linux kernel contained a buffer overflow when handling fragmented packets. A remote attacker could use this to possibly execute arbitrary code with administrative privileges. (CVE-2016-8633) Andrey Konovalov discovered that a divide-by-zero error existed in the TCP stack implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14106)
