Description

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 memory containing sensitive information. This vulnerability is limited to Squid deployments that have explicitly enabled ICP support.
