Libicns Faces Iconic Overflow Meltdown: Beware the .icns Files!
Libicns v0.8.1 goes wild when parsing .icns files, causing signed integer overflow. Malicious files can crash applications faster than you can say “overflow.” Just another day in the life of software parsing!
Hot Take:
Who knew that a tiny pixelated apple icon could bring down the mighty tower of your computer’s sanity?

Time to send it back to byte school for a refresher on numerical etiquette!

- Libicns version 0.8.1 suffers from a signed integer overflow vulnerability.
- The issue arises when parsing .icns files with particular byte values.
- The overflow could lead to application crashes or memory corruption.
