Timo Sirainen discovered several problems in EPIC, a popular client for Internet Relay Chat (IRC). A malicious server could craft special reply strings, triggering the client to write beyond buffer boundaries. This could lead to a denial of service if the client only crashes, but may also lead to executing of arbitrary code under the user id of the chatting user.
