CVE-2025-13470

A flaw was found in RNP. This vulnerability allows for the trivial decryption of data encrypted using public-key encryption, fully compromising confidentiality, via an uninitialized symmetric session key in Public-Key Encrypted Session Key PKESK packets, which results in an all-zero byte array...

CVE-2025-13470

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...

CVE-2025-13470

CVE-2025-13470 affects RNP prior to 0.18.1, where a refactoring regression left the symmetric session key for PKESK packets uninitialized beyond zeroing. The result is an all-zero session key for PKESK, allowing data encrypted with public-key encryption to be decrypted trivially, compromising con...
