CRITICAL:
Moderately critical

DESCRIPTION:
Tan Chew Keong has discovered a vulnerability in ICEOWS, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an input validation error in
IceGUI.DLL when processing ACE archives. This can be exploited to
cause a stack-based buffer overflow via a specially crafted ACE
archive with an overly large filename size in the header.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 4.20b. Other versions may
also be affected.

SOLUTION:
Do not extract or open untrusted .ACE archives.
