QID 355331: Amazon Linux Security Advisory for squid : ALAS2-2023-2063

An issue was discovered in squid before 4.12 and 5.x before 5.0.3.
Due to use of a potentially dangerous function, squid and the default certificate validation helper are vulnerable to a denial of service when opening a tls connection to an attacker-controlled server for https.
This occurs because unrecognized error values are mapped to null, but later code expects that each error value is mapped to a valid error string. (
