Monkey HTTP Server before 1.5.3, when the File Descriptor Table (FDT) is enabled and custom error messages are set, allows remote attackers to cause a denial of service (file descriptor consumption) via an HTTP request that triggers an error message.
The Mandril security plugin in Monkey HTTP Daemon (monkeyd) before 1.5.0 allows remote attackers to bypass access restrictions via a crafted URI, as demonstrated by an encoded forward slash.
Stack-based buffer overflow in the mk_request_header_process function in mk_request.c in Monkey HTTP Daemon (monkeyd) before 1.2.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted HTTP header.
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.
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.
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 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.
