  "details": "In RNP version 0.18.0 a refactoring regression causes the symmetric  session key used for Public-Key Encrypted Session Key (PKESK) packets to  be left uninitialized except for zeroing, resulting in it always being  an all-zero byte array.  Any data encrypted using public-key encryption  in this release can be decrypted trivially by supplying an all-zero  session key, fully compromising confidentiality.  The vulnerability affects only public key encryption (PKESK packets).  Passphrase-based encryption (SKESK packets) is not affected.  Root cause: Vulnerable session key buffer used in PKESK packet generation.    The defect was introduced in commit `7bd9a8dc356aae756b40755be76d36205b6b161a` where initialization  logic inside `encrypted_build_skesk()` only randomized the key for the  SKESK path and omitted it for the PKESK path.",
