Zipgenius Multiple Archive Handling Buffer Overflow

**kingaff** · 23-Feb-2007, 05:55 AM

Code:

Affected Software

ZipGenius Version 5.5.1.468 and 6.0.2.1041.

Prior versions may also be affected.

Description of Vulnerability

1) A boundary error exists in "zipgenius.exe", "zg.exe", "zgtips.dll",
and "contmenu.dll" when reading the filename of a compressed file
from a ZIP archive. This can be exploited to cause a stack-based
buffer overflow when a malicious archive containing a file with an
overly long filename is read either in ZipGenius or from Windows
Explorer.

2) A boundary error exists in "zipgenius.exe" when handling the
original name of a UUE/XXE/MIM encoded file. This can be exploited
to cause a stack-based buffer overflow when a malicious UUE/XXE/MIM
archive containing an encoded file with an overly long filename is
opened.

3) A boundary error exists in "unacev2.dll" when extracting an ACE
archive containing a file with an overly long filename. This can be
exploited to cause a stack-based buffer overflow when a malicious
ACE archive is extracted using "zipgenius.exe" or "zg.exe".

Njoy...
