Overview
Affected versions of this package are vulnerable to Double Free in the kerberos_AcceptSecurityContext process. An attacker can cause a crash of the client application by triggering a failed authentication attempt during NLA connection teardown on systems configured with Kerberos or Kerberos U2U. This is only exploitable if Kerberos or Kerberos U2U is enabled and a failed authentication occurs during NLA connection teardown.
