    Package        : epic4
    Vulnerability  : buffer overflow
    Problem-Type   : remote
    Debian-specific: no
    CVE Id         : CAN-2003-0328
    
    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.
    
    For the stable distribution (woody) this problem has been fixed in
    version 1.1.2.20020219-2.2.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 1.1.11.20030409-2.
    
    We recommend that you upgrade your epic4 package.
