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.
