In versions 2.3.3 and below, untrusted data is extracted from the user-controlled HTTP Proxy-Authorization header and passed to Extension::try_from and flows into parse_ttl_extension where it is parsed as a TTL value. If an attacker supplies a TTL of zero (e.g. by using a username such as \u0027configuredUser-ttl-0\u0027), the modulo operation \u0027timestamp % ttl\u0027 will cause a division by zero panic, causing the server to crash causing a denial-of-service. This is fixed in version 2.4.0."
