Monkey HTTP Daemon (monkeyd) before 1.2.2 allows remote attackers to cause a denial of service (infinite loop) via an offset equal to the file size in the Range HTTP header.

Monkey HTTP Daemon 0.9.3 retains the supplementary group IDs of the root account during operations with a non-root effective UID, which might allow local users to bypass intended file-read restrictions by leveraging a race condition in a file-permission check.

Cross-site scripting (XSS) vulnerability in the Directory Listing plugin in Monkey HTTP Daemon (monkeyd) 1.2.2 allows attackers to inject arbitrary web script or HTML via a file name.

Monkey HTTP Daemon 0.9.3 might allow local users to overwrite arbitrary files via a symlink attack on a PID file, as demonstrated by a pathname different from the default /var/run/monkey.pid pathname.

Monkey HTTP Daemon 0.9.3 uses a real UID of root and a real GID of root during execution of CGI scripts, which might allow local users to gain privileges by leveraging cgi-bin write access.

The mk_request_header_process function in mk_request.c in Monkey 1.1.1 allows remote attackers to cause a denial of service (thread crash and service outage) via a '\0' character in an HTTP request.
