> DESCRIPTION:
> Rapid7 has reported a vulnerability in NVIDIA Binary Graphics Driver
> for Linux, which can be exploited by malicious, local users to gain
> escalated privileges and potentially by malicious people to
> compromise a user's system.
> 
> A boundary error when performing accelerated rendering of glyphs can
> be exploited to cause a buffer overflow via a specially crafted short
> sequence of user-supplied glyphs.
> 
> Successful exploitation allows execution of arbitrary code with
> "root" privileges.
> 
> The vulnerability is reported in versions 8774 and 8762. Other
> versions may also be affected.
>
