IBM Lotus Domino Accept-Language buffer overflow

ibm-lotusdomino-acceptlanguage-bo (42552) The risk level is classified as HighHigh Risk


IBM Lotus Domino is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the Lotus Domino Web Server when the Domino Web server task is enabled. By sending a specially-crafted HTTP GET request with an overly long "Accept-Language" header, a remote attacker could overflow a buffer and execute arbitrary code on the system with SYSTEM privileges or cause the server to crash.
