[v2.7] lighttpd: Log injection vulnerability in mod_auth (CVE-2015-3200)
When basic HTTP authentication base64 string does not contain colon character (or contains it after NULL byte - can be inserted inside base64 encoding), then that ituation is logged with a string “: is missing in ” and the simply decoded base64 string. This means that new lines, NULL byte and everything else can be encoded with base64 and are then inserted to logs as they are after decoding.
