Part 3/9:
However, as research commenced, it became apparent that information surrounding this bug was scarce. Despite extensive searching, concrete proof of concept or any documented research was elusive. Documentation indicated that the vulnerability resided within Szip's handling of various archive formats, highlighting integer underflow as a critical element that could allow hackers to gain remote code execution.
Understanding the Technical Background
Before diving deep into the code, it was necessary to understand the foundational elements of Szip. The tool not only supports multiple archive formats, including the well-known 7zip proprietary format but also utilizes the Z standard for decompression—a process inherently relying on programming for any rational file handling.
