Integer signedness error in the base64_decode function in the HTTP
authentication functionality (http_auth.c) in lighttpd 1.4 before 1.4.30
and 1.5 before SVN revision 2806 allows remote attackers to cause a denial
of service (segmentation fault) via crafted base64 input that triggers an
out-of-bounds read with a negative index.
