virtualbox_e1000_0day

Why I like VirtualBox and it has nothing to do with why I publish a 0day vulnerability. The reason is my disagreement with contemporary state of infosec, especially of security research and bug bounty: 1. Wait half a year until a vulnerability is patched is considered fine. 2. In the bug bounty...

QEMU (e1000): Buffer Overflow

A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short frames was dropped from individual network devices and moved to the net core code. The issue stems from the device's receive code still being able to process a short frame in loopback mode. This...
