Descriptions
kbx/keybox-search.c in GnuPG before 1.4.19, 2.0.x before 2.0.27, and 2.1.x before 2.1.2 does not properly handle bitwise left-shifts, which allows remote attackers to cause a denial of service (invalid read operation) via a crafted keyring file, related to sign extensions and "memcpy with overlapping ranges."
El archivo kbx/keybox-search.c en GnuPG versiones anteriores a 1.4.19, versiones 2.0.x anteriores a 2.0.27 y versiones 2.1.x anteriores a 2.1.2, no maneja apropiadamente los cambios a la izquierda bit a bit, lo que permite a atacantes remotos causar una denegación de servicio (operación de lectura no válida) por medio de un archivo de llavero diseñado, relacionado con extensiones de signo y "memcpy with overlapping ranges."
