Описание
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.
Отчет
The p11-kit library is primarily intended to be used locally, in which case the attacker needs to have sufficient permission to access the p11-kit communication. Although there may be use cases of p11-kit being used with a remote entity, all parties must be considered trusted. As a result, Red Hat considers this vulnerability with a Medium severity.
