US-CERT/NIST reports:
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.
