First, the RPC library could call an uninitialized function pointer, which created a security vulnerability for kadmind(8). Second, the GSS-API "mechglue" layer could fail to initialize some output pointers, causing callers to attempt to free uninitialized pointers. This caused another security vulnerability in kadmind(8).
