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).

This update for openfortivpn to version 1.12.0 fixes the following issues :

  - CVE-2020-7043: Fixed a TLS Certificate CommonName NULL     Byte Vulnerability (boo#1165301).

  - CVE-2020-7042: Fixed use of uninitialized memory in     X509_check_host (boo#1165300).

  - CVE-2020-7041: Fixed incorrect use of X509_check_host     (boo#1165299).

Update to latest upstream version to fix CVE-2020-7041, CVE-2020-7042 and CVE-2020-7043.
