MNBSD-2024-2: Certificate revocation list fetch(1) option fails

Description

The fetch(3) library uses environment variables for passing certain information, including the revocation file pathname. The environment variable name used by fetch(1) to pass the filename to the library was incorrect, in effect ignoring the option. Fetch would still connect to a host presenting a certificate included in the revocation file passed to the --crl option.

Affected Versions

Specific versions:

• 2.2.0
• 2.2.1

Recommendations

The certificate revocation list file can be specified by the SSL_CRL_FILE fetch(3) environment variable rather than using the --crl option to fetch(1). Update to MidnightBSD 3.2.1 release by using the normal update procedure.
