syslog-ng is an enhanced log daemo. Prior to version 4.8.2, "tls_wildcard_match()" matches on certificates such as "foo.*.bar" although that is not allowed. It is also possible to pass partial wildcards such as "foo.a*c.bar" which glib matches but should be avoided / invalidated. This issue could have an impact on TLS connections, such as in man-in-the-middle situations. Version 4.8.2 contains a fix for the issue.
