DESCRIPTION:
A vulnerability has been discovered in Enzip, which can be exploited
by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when processing
file name entries inside an archive. This can be exploited to cause a
heap-based buffer overflow via an overly long file name entry in a
specially crafted ZIP archive.

Successful exploitation allows execution of arbitrary code, but
requires tricking a user into extracting the archive's contents.

The vulnerability is confirmed in version 3.00. Other versions may
also be affected.

SOLUTION:
Do not extract archive files from untrusted sources.
