CVE-2026-33515

A flaw was found in Squid, a caching proxy for the Web. Due to improper input validation, Squid is vulnerable to an out-of-bounds read when handling Internet Cache Protocol ICP traffic. A remote attacker can exploit this by sending invalid ICP requests, potentially receiving small amounts of memo...

CVE-2026-32748

A flaw was found in Squid. A remote attacker can exploit this vulnerability by sending specially crafted ICP Internet Cache Protocol traffic. This can lead to a Denial of Service DoS due to premature resource release and use-after-free vulnerabilities. This attack is possible in Squid deployments...
