Directory traversal vulnerability in Mathopd 1.4.x and 1.5.x before 1.5p7, when configured with the * construct for mass virtual hosting, allows remote attackers to read arbitrary files via a crafted Host header.
Buffer overflow in the prepare_reply function in request.c for Mathopd 1.2 through 1.5b13, and possibly earlier versions, allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via an HTTP request with a long path.
