From VID-620685D6-0AA3-11EA-9673-4C72B94353B5:

Squid Team reports:

Problem Description: Due to incorrect data management Squid is

vulnerable to a information disclosure when processing HTTP Digest

Authentication.

Severity: Nonce tokens contain the raw byte value of a pointer which sits

within heap memory allocation. This information reduces ASLR protections

and may aid attackers isolating memory areas to target for remote code

execution attacks.
