Background
Taglib is a library for reading and editing metadata in various audio file formats. It provides a convenient way to extract information such as artist, album, and title from audio files. However, a vulnerability has been discovered in taglib that could allow an attacker to trigger a heap-based buffer over-read by exploiting a crafted audio file.
