Summary

Details

A flaw was found in p11-kit. The RPC message attribute parsing functions p11rpcmessagegetattribute() and p11rpcmessagegetattributearrayvalue() form a mutually-recursive call chain with no recursion depth limit when processing nested CKAWRAPTEMPLATE, CKAUNWRAPTEMPLATE, and CKADERIVETEMPLATE attributes. An unauthenticated attacker with local access to the p11-kit RPC Unix domain socket can send a specially crafted request with deeply nested template attributes, causing stack exhaustion and crashing the p11-kit server process and its dependent services.
