FreeBSD : xen-kernel -- x86: Mishandling of instruction pointer truncation during emulation (49211361-ba4d-11e6-ae1b-002590263bf5)
The Xen Project reports : When emulating HVM instructions, Xen uses a small i-cache for fetches from guest memory. The code that handles cache misses does not check if the address from which it fetched lies within the cache before blindly writing to it. As such it is possible for the guest to...

shopify-scripts: Struct type confusion RCE
Heya! I've been poking at mruby a bit more and I've found a vulnerability that allows an attacker to take control of the instruction pointer. I've attached a proof of concept script that when run in mruby will jump to 0x0000133713371337 and segfault. While the proof of concept script just jumps t...
