A recent security advisory announced today by Rapid7 explains, "the NVIDIA Binary Graphics Driver for Linux is vulnerable to a buffer overflow that allows an attacker to run arbitrary code as root. This bug can be exploited both locally or remotely (via a remote X client or an X client which visits a malicious web page). A working proof-of-concept root exploit is attached to this advisory." The advisory goes on to note that the FreeBSD and Solaris binary drivers are also likely vulnerable to the same flaw and cautions, "it is our opinion that NVIDIA's binary driver remains an unacceptable security risk based on the large numbers of reproducible, unfixed crashes that have been reported in public forums and bug databases."

Chad Loder [bio], Rapid7's Manager of Engineering, explained that NVIDIA has known about this bug in their binary driver for some time, "the link in the advisory is the earliest thread in which we could find an NVIDIA employee publicly acknowledging the bug, although it was reported back in 2004 and has probably existed even longer." Regarding the decision to announce the exploit to the public Chad explained, "I expect (or hope) that NVIDIA will fix the defect in their binary drivers quickly. I don't know anything about their development process or where their Linux drivers fit into their priority list. It seems that the majority of Linux users are perfectly willing to accept bugs in binary blob drivers from hardware vendors, so there is little incentive for NVIDIA to change their process."
