Just days after patching the DYLD_PRINT_TO_FILE vulnerability with a new OS X point release, Apple's desktop operating system has been hit with yet another zero-day exploit that would allow an attacker to gain root access without using a password.

The exploit was discovered by Italian developer Luca Todesco, who relies on a combination of attacks — including a null pointer dereference in OS X's IOKit — to drop a proof-of-concept payload into a root shell. It affects every version of OS X Yosemite, but seems to have been mitigated in OS X El Capitan, which is nearing release.

Todesco did not disclose the problem to Apple before sharing it publicly early Sunday, so it remains to be seen how quickly the company will respond.
