Description

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.

Affected configurations

• squid-cache squid (>= 3.1 <= 3.5.28) • squid-cache squid (>= 4.0 < 4.12) • squid-cache squid (>= 5.0 < 5.0.3) • fedoraproject fedora 31 • netapp cloud manager
