OpenBSD 3.5-3.6 - Denial of Service via TCP Timestamp Option

Title source: llm
STIX 2.1

Description

The TCP stack (tcp_input.c) in OpenBSD 3.5 and 3.6 allows remote attackers to cause a denial of service (system panic) via crafted values in the TCP timestamp option, which causes invalid arguments to be used when calculating the retransmit timeout.
