More information:

Jeremy Nelson discovered a remotely exploitable buffer overflow in EPIC4, a popular client for Internet Relay Chat (IRC). A malicious server could craft a reply which triggers the client to allocate a negative amount of memory. 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.
