Does this matter?
Lower severity and a low EPSS score (1.58%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later. tunnel.c mishandles certificate validation because the hostname check operates on uninitialized memory. The outcome is that a valid certificate is never accepted (only a malformed certificate may be accepted).
