Upgrade Debian:14 botan3 to version 3.13.0+dfsg-2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream botan3 package and not the botan3 package as distributed by Debian.
See How to fix? for Debian:14 relevant fixed versions and status.
Botan is a C++ cryptography library. From 1.11.34 until 3.13.0, the botan ocsp_check command requested an OCSP response from a certificate's Authority Information Access URL without verifying the response signature or authorizing the signer. A malicious responder or on-path attacker could return a matching and timely GOOD response with an empty, invalid, or unauthorized signature, causing a revoked certificate to produce exit status 0 and OCSP check OK output. Only the command-line interface is affected. This issue is fixed in version 3.13.0.
