DescriptionNVD

An issue was discovered in p11-kit 0.21.1 through 0.23.21. A heap-based buffer over-read has been discovered in the RPC protocol used by thep11-kit server/remote commands and the client library. When the remote entity supplies a byte array through a serialized PKCS#11 function call, the receiving entity may allow the reading of up to 4 bytes of memory past the heap allocation.

AnalysisAI
