https://notcve.org/view.php?id=CVE-2019-16058
An issue was discovered in the pam_p11 component 0.2.0 and 0.3.0 for OpenSC. If a smart card creates a signature with a length longer than 256 bytes, this triggers a buffer overflow. This may be the case for RSA keys with 4096 bits depending on the signature scheme. Se descubrió un problema en el componente pam_p11 versiones 0.2.0 y 0.3.0 para OpenSC. Si una tarjeta inteligente crea una firma con una longitud mayor a 256 bytes, esto desencadena un desbordamiento de búfer. • http://www.openwall.com/lists/oss-security/2019/09/12/1 https://github.com/OpenSC/pam_p11/commit/d150b60e1e14c261b113f55681419ad1dfa8a76c • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
