Description

This security bulletin contains information about 1 vulnerability.


1) Improper Check for Certificate Revocation (CVE-ID: CVE-2024-45289)

CWE-ID: CWE-299 - Improper Check for Certificate Revocation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error in fetch(1) when handling certificate revocation file passed via the "--crl" option. The environment variable name used by fetch(1) to pass the filename to the library was incorrect, in effect ignoring the option. As a result, the library will still connect to a host presenting a certificate that was included into the revocation list.
