Certain malformed OpenPGP messages could trigger incorrect parsing of PKESK/SKESK packets due to a bug in the Ribose RNP library used by Thunderbird up to version 102.9.1, which would cause the Thunderbird user interface to hang. The issue was discovered using Google's oss-fuzz.
Ribose RNP before 0.15.1 does not implement a required step in a cryptographic algorithm, resulting in weaker encryption than on the tin of the algorithm.
Ribose RNP before 0.16.3 sometimes lets secret keys remain unlocked after use.
