CVE-2020-29363 HIGH

Published: 2020-12-16 | Last Modified: 2024-11-21 | Status: Modified

Description

An issue was discovered in p11-kit 0.23.6 through 0.23.21. A heap-based buffer overflow has been discovered in the RPC protocol used by p11-kit server/remote commands and the client library. When the remote entity supplies a serialized byte array in a CK_ATTRIBUTE, the receiving entity may not allocate sufficient length for the buffer to store the deserialized value.

Additional Descriptions (1)

Se detectó un problema en p11-kit versiones 0.23.6 hasta 0.23.21. Se ha detectado un desbordamiento de búfer en la región heap de la memoria en el protocolo RPC usado por los comandos remotos del servidor p11-kit y la biblioteca cliente. Cuando la entidad remota proporciona una matriz de bytes serializados en un CK_ATTRIBUTE, es posible que la entidad receptora no asigne una longitud suficiente para que el búfer almacene el valor deserializado
