What is CVE-2022-28550?

The jhead utility, developed by Matthias Wandel, is susceptible to a buffer overflow vulnerability in version 3.06. This vulnerability occurs when the utility processes certain input commands ('&i' or '&o') without proper boundary checks on a stack buffer. This oversight allows for the potential overflow when multiple instances of these commands are provided, potentially leading to unexpected behavior or exploitation. Users and administrators should apply necessary patches and ensure they are using the latest version to mitigate this risk.
