Ubuntu 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 : JOSE for C/C++ vulnerability (USN-6307-1)

high Nessus Plugin ID 180187

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by a vulnerability as referenced in the USN-6307-1 advisory.

 - 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). (CVE-2023-37464)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libcjose-dev and / or libcjose0 packages.
