Aaron Adams presented this talk at HITB Phuket on the 24th August 2023. The talk
detailed how NCC Exploit Development Group (EDG) in Pwn2Own 2022 Toronto was
able to exploit two different PostScript vulnerabilities in Lexmark printers.
The presentation is a good primer for those interested in further researching
the Lexmark PostScript stack, and also those interested in how PostScript
interpreter exploitation can be approached in general.
