Descriptions

gpgv in GnuPG before 1.4.2.1, when using unattended signature verification, returns a 0 exit code in certain cases even when the detached signature file does not carry a signature, which could cause programs that use gpgv to assume that the signature verification has succeeded. Note: this also occurs when running the equivalent command "gpg --verify".

gpgv en GnuPG en versiones anteriores a 1.4.2.1, cuando se utiliza verificación de firma desatendida, devuelve un código de salida 0 en algunos casos, incluso cuando el archivo de firma acompañante no lleva una firma, esto puede provocar que los programas que usen gpgv asuman que la verificación de la firma ha tenido éxito. Nota: Esto también ocurre cuando se ejecuta el comando equivalente "gpg --verify".
