CVE-2020-29363
Estado: ModificadaAlta (7.5)—
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.
