Description Stoyan Manolov 2023-07-17 08:51:03 UTC

CVE-2023-37464

OpenIDC/cjose is a C library implementing the Javascript Object Signing and
Encryption (JOSE). The AES GCM decryption routine incorrectly uses the Tag
length from the actual Authentication Tag provided in the JWE. The spec  says
that a fixed length of 16 octets must be applied. Therefore this bug allows an
attacker to provide a truncated Authentication Tag and to modify the JWE
accordingly. Users should upgrade to a version >= 0.6.2.2. Users unable to
upgrade should avoid using AES GCM encryption and replace it with another
encryption algorithm (e.g. AES CBC).
