Overview
Affected versions of this package are vulnerable to Stack-based Buffer Overflow in the RPCSEC_GSS packet validation process. An attacker can execute arbitrary code in kernel or user space by sending specially crafted packets to the affected server. This is only exploitable if the kgssapi.ko module is loaded in the kernel or if an application has librpcgss_sec loaded and runs an RPC server.
