SecurityTracker URL:  http://securitytracker.com/id/1015265
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Nov 24 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 5.0 Build 4285
Description:   A vulnerability was reported in ZipStar. A remote user can cause arbitrary code to be executed on a target user's system.

A remote user can create a specially crafted ZIP file that, when processed by the target user, will trigger a buffer overflow and execute arbitrary code. The code will run with the privileges of the target user.

A specially crafted full pathname of a file in a ZIP archive can trigger a stack overflow in CxZIP60.dll and CxZIP60u.dll.

The vendor was notified on November 3, 2005.

Tan Chew Keong of Secunia Research discovered these vulnerabilities.

Impact:   A remote user can create a file that, when processed by the target user, will execute arbitrary code on the target user's system with the privileges of the target user.
Solution:   The vendor has issued a fixed version (5.10 Build 4460).
Vendor URL:  www.speedproject.de/ (Links to External Site)

3) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in various
SpeedProject products, which can be exploited by malicious people to
compromise a user's system.

1) A boundary error exists in CxZIP60.dll and CxZIP60u.dll due to the
unsafe use of the "lstrcat()" function when constructing the full
pathname of a file that is extracted from a ZIP archive. This can be
exploited to cause a stack-based buffer overflow and allows arbitrary
code execution when a specially crafted archive is extracted.

The vulnerability has been confirmed in the following products.
* ZipStar 5.0 Build 4285
* Squeez 5.0 Build 4285
* SpeedCommander 11.0 Build 4430
* SpeedCommander 10.51 Build 4430

2) A boundary error exists in CxUux60.dll and CxUux60u.dll due to
the unsafe use of the "lstrcpy()" function when constructing the
full pathname of the file that is decoded from a UUE file. This can
be exploited to cause a stack-based buffer overflow and allows
arbitrary code execution when a specially crafted UUE file is
decoded.

The vulnerability has been confirmed in the following products.
* Squeez 5.0 Build 4285
* SpeedCommander 11.0 Build 4430
* SpeedCommander 10.51 Build 4430

======================================================================
