Prior to version 0.27.0, feeding a crafted input to the fuzz_pkcs15_reader harness causes OpenSC to perform an out-of-bounds heap read in the X.509/SPKI handling path. Specifically, sc_pkcs15_pubkey_from_spki_fields() allocates a zero-length buffer and then reads one byte past the end of that allocation. This issue has been patched in version 0.27.0."},{"lang":"es","value":"OpenSC es un conjunto de herramientas y middleware de código abierto para tarjetas inteligentes. Antes de la versión 0.27.0, al introducir una entrada manipulada en el arnés fuzz_pkcs15_reader, OpenSC realiza una lectura de pila fuera de límites en la ruta de manejo de X.509/SPKI. Específicamente, sc_pkcs15_pubkey_from_spki_fields() asigna un búfer de longitud cero y luego lee un byte más allá del final de esa asignación.
