PicoZip ZipInfo.dll Filename Handling Buffer Overflow

High Nessus Plugin ID 21697


The remote Windows host contains an application that is affected by a buffer overflow.


The remote host is running PicoZip, a file compression utility for Windows.

According to the registry, the version of PicoZip installed on the remote Windows host fails to properly check the size of filenames before copying them into a finite-sized buffer within the 'zipinfo.dll' info tip shell extension. Using a specially crafted ACE, RAR, or ZIP file, an attacker may be able to exploit this issue to execute arbitrary code on the affected host subject to the privileges of the user running the affected application.


Upgrade to PicoZip version 4.02 or later.
