A vulnerability has been identified in GnuPG, which could be exploited by attackers to bypass security restrictions and procedures. This flaw is due to an error in the verification of non-detached signatures when handling certain illegal signature formats, which could be exploited by attackers to inject arbitrary data into a digitally-signed message, allowing them to bypass authentication systems, or impersonate another user.
