An issue was discovered in Squid before 5.0.2. A remote attacker can replay
a sniffed Digest Authentication nonce to gain access to resources that are
otherwise forbidden. This occurs because the attacker can overflow the
nonce reference counter (a short integer). Remote code execution may occur
if the pooled token credentials are freed (instead of replayed as valid
credentials).
