Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 30bda1c3-369b-11f1-b51c-6dd25bec137b advisory.

 Seth Larson reports:
 HTTP proxy via CONNECT tunneling doesn't sanitize CR/LF (CVE-2026-1502).
