NVD Description

Note: Versions mentioned in the description apply only to the upstream p11-kit package and not the p11-kit package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

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.
