Name of the Vulnerable Software and Affected Versions OpenBSD version 3.0

Description The issue allows remote attackers to determine if a port is being filtered due to the TTL being different from the default TTL in the RST packet. This occurs because the PF in OpenBSD 3.0 with the return-rst rule sets the TTL to 128.

Recommendations For OpenBSD version 3.0, consider modifying the PF rule to set the TTL to the default value to prevent attackers from determining if a port is being filtered.
