CVE-2017-18589 — Vulnerability in cookie — CVE Details

HIGH

Large cookie Max-Age values can cause a denial of service

Published May 6, 2017Updated November 8, 2023Source: osv

Summary

Affected versions of this crate use the `time` crate and the method `Duration::seconds` to parse the `Max-Age` duration cookie setting. This method will panic if the value is greater than 2^64/1000 and less than or equal to 2^64, which can result in denial of service for a client or server. This flaw was corrected by explicitly checking for the `Max-Age` being in this integer range and clamping the value to the maximum duration value.
