  SpeedProject Products ZIP and UUE File Extraction Buffer Overflow
------------------------------------------------------------------------

SUMMARY

" <http://www.speedproject.de/enu/speedcommander/index.html>
SpeedCommander is a comfortable file manager."
" <http://www.speedproject.de/enu/squeez/index.html> Squeez is an
extremely fast file compression application, supporting 13 different
compression algorithms."
" <http://www.speedproject.de/enu/zipstar/index.html> ZipStar is our FREE
archiving application for home users."

Lack of length validation allow attackers to cause the SpeedProject
program to execute arbitrary code.

DETAILS

Vulnerable Systems:
 * ZipStar version 5.0 Build 4285
 * Squeez version 5.0 Build 4285
 * SpeedCommander version 11.0 Build 4430
 * SpeedCommander version 10.51 Build 4430

Immune Systems:
 * SpeedCommander version 10.52 Build 4450
 * SpeedCommander version 11.01 Build 4450
 * Squeez version 5.10 Build 4460
 * ZipStar version 5.10 Build 4460

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
also exists with CxUux60.dll and CxUux60u.dll library that handles UUE
decoding.
