| There’s nothing like a zero-day to ruin the holiday break, but that’s just what may be in store for engineers at Nvidia after a researcher discovered a new vulnerability in the Nvidia Display Driver Service. The flaw could hand over administrator privileges on Windows machines to an attacker.
Peter Winter-Smith, formerly with the NGS Software of the U.K., posted details of the vulnerability and exploit to Pastebin. In it, he explains that the service is vulnerable to a stack buffer overflow that bypasses data execution prevention (DEP) and address space layout randomization (ASLR) running in the Windows operating system since Windows Vista.
“The service listens on a named pipe (\pipe\nsvr) which has a NULL DACL configured, which should mean that any logged on user or remote user in a domain context (Windows firewall/file sharing permitting) should be able to exploit this vulnerability,” Winter-Smith wrote on Pastebin. “The buffer overflow occurs as a result of a bad memmove operation.” Read More .. |
