Updated cjose packages fix a security vulnerability

Publication date: 18 Dec 2023
Modification date: 18 Dec 2023
Type: security
Affected Mageia releases : 8 , 9
CVE: CVE-2023-37464

Description

The updated packages fix a security vulnerability:
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. (CVE-2023-37464)
