MIMEDefang 3.7.2
Security
- CVE-2026-120211 - PID file symlink following (privileged file overwrite).
- CVE-2026-120304 - anonymize_uri() regular expression denial of service.
- CVE-2026-120305 - md_spf_verify()/md_authres() regular expression denial of service.
- Header injection hardening: header names and values that the filter returns are now validated before they are
passed to the MTA. Invalid header names are logged and dropped.
- MTA-STS (RFC 8461): policy fetches now allow HTTPS only, follow no redirects and stop at 64 KB and the domain is validated before it is used in the policy URL.
Bug fixes and improvements
- re_match_in_7zip_directory: correctly parses listings of solid archives, skips directory entries and no longer hangs on archives with encrypted headers.
- re_match_in_rar_directory: the file list is now read up to the closing separator.
- Mail::MIMEDefang::Async: faster parsing of the SpamAssassin X-Spam-Status header.
- Mail::MIMEDefang::Net: improve ipv6 checks.
