220 - Windows Kernel Bugs, Safari Integer Underflow, and CONSTIFY [Binary Exploitation Podcast]

Diving right into some binary exploitation issues this week. Starting wtih a look at a rare sort of curl vulnerability where a malicious server could compromise a curl user. Then we take a look at a pretty straight-forward type confusion in Windows kernel code, and an integer underflow in Safari with some questionable exploitation. Ending the episode with some thoughts on how impactful grsecurity's "constify" mitigation could be.
