Re: [Qemu-devel] Fuzzing

[Catena cyber]

Hi Alex,

I am not asking for any specific action.
I just wanted to let you know about this fuzzing work of mine, in case that 
proves helpful to qemu.
Have you been fuzzing qemu ? And more specifically the code for the different 
architectures arm, sparc, etc…

Take care,
Philippe
