DESCRIPTION:
Secunia Research has discovered a vulnerability in Abakt, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when listing the
contents of a ZIP archive. This can be exploited to cause a
stack-based buffer overflow when a malicious ZIP archive containing a
file with an overly long filename is opened.

The vulnerability is related to:
SA19945

Successful exploitation allows execution of arbitrary code but
requires that the user is e.g. tricked into opening a malicious ZIP
archive from within the "Restore Zip Archive" functionality.

The vulnerability has been confirmed in version 0.9.2 and
0.9.3-beta1. Prior versions may also be affected.

SOLUTION:
The vulnerability has been fixed in 0.9.3-RC1.
