Q: Which products are affected by CVE-2020-14058?

5 products: squid-cache squid, squid-cache squid, squid-cache squid, fedoraproject fedora, netapp cloud manager.

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.
