darkhttpd before 1.15 uses strcmp (which is not constant time) to verify authentication, which makes it easier for remote attackers to bypass authentication via a timing side channel.

darkhttpd through 1.15 allows local users to discover credentials (for --auth) by listing processes and their arguments.

A flaw was found in darkhttpd. Invalid error handling allows remote attackers to cause denial-of-service by accessing a file with a large modification date. The highest threat from this vulnerability is to system availability.
