CVE-2019-18679 is an information disclosure vulnerability affecting Squid versions 2.x, 3.x, and 4.x through 4.8, including products from Canonical, Debian, and Fedora. This flaw stems from incorrect data management during HTTP Digest Authentication, where nonce tokens expose raw pointer values from heap memory. Rated 7.5 HIGH on CVSS, this vulnerability allows unauthenticated attackers over the network to reduce Address Space Layout Randomization (ASLR) protections, potentially aiding in subsequent remote code execution attempts. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
