An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to
incorrect data management, it is vulnerable to information disclosure when
processing HTTP Digest Authentication. Nonce tokens contain the raw byte
value of a pointer that sits within heap memory allocation. This
information reduces ASLR protections and may aid attackers isolating memory
areas to target for remote code execution attacks.
