The strHdrAcptLangGetItem function in errorpage.cc in Squid 3.2.x before 3.2.9 and 3.3.x before 3.3.3 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a "," character in an Accept-Language header.

Security readout for executives and security teams

A specially malformed browser language header could make vulnerable Squid proxy versions spin in an infinite loop, consuming CPU and denying service. The issue affects Squid 3.2.x before 3.2.9 and 3.3.x before 3.3.3. The sources do not indicate data theft or code execution. Exposure is limited to organizations still running affected Squid 3.2.x or 3.3.x builds, especially proxies reachable by untrusted clients. Confirm vendor or distribution backports before judging patched status by upstream version alone. Treat as a focused availability risk. Prioritize remediation where Squid is internet-facing, supports critical outbound traffic, or lacks access controls. For modern environments not running these old Squid branches, urgency is low after inventory confirmation. Mitigation focus: Upgrade Squid 3.2.x to 3.2.9 or later.; Upgrade Squid 3.3.x to 3.3.3 or later.; Check vendor or distribution advisories for supported backported fixes..
