Name of the Vulnerable Software and Affected Versions OpenBSD versions 3.5 through 3.6

Description The issue allows remote attackers to cause a denial of service, resulting in a system panic. This is achieved by sending crafted values in the TCP timestamp option, which leads to invalid arguments being used when calculating the retransmit timeout.

Recommendations For OpenBSD versions 3.5 and 3.6, consider disabling the TCP timestamp option as a temporary workaround until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
