Bugs often rear themselves in sparcely-maintained, but prominently used infrastructure.
Often, such infrastructure takes the form of small, little-known libraries handling specific functionality for larger, well-known projects.
One such example is libcue and CVE-2023-43641.
In real life, the actual attack vector was a part of gnome.
Here, we've provided the parse_cue program.
Understand this bug, understand the software around it, and trigger the crash.
If you can segfault parse_cue, you will earn the flag!
