Medium Nessus Plugin ID 57411


The remote FreeBSD host is missing a security-related update.


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.


Update the affected package.
