Exploitation Summary
EIP tracks 1 public exploit for CVE-2016-1576. PoCs published by halfdog.
AI-analyzed exploit summary This exploit leverages a privilege escalation vulnerability in Ubuntu Wily by mounting a FUSE filesystem with a SUID binary, then using overlayfs to trigger a copy_up operation that creates a real SUID binary. The PoC includes custom C programs to demonstrate the attack chain.
Description
The overlayfs implementation in the Linux kernel through 4.5.2 does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an overlayfs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program.
