Notifications for a CVE
Stay informed of any changes for a specific CVE.
CVE Descriptions
The NVIDIA driver before 307.78, and Release 310 before 311.00, in the NVIDIA Display Driver service on Windows does not properly handle exceptions, which allows local users to gain privileges or cause a denial of service (memory overwrite) via a crafted application.
CVE Informations
Related Weaknesses
| Weakness Name | Source | |
|---|---|---|
| Improper Restriction of Operations within the Bounds of a Memory Buffer The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
Metrics

EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

'Name' => 'Nvidia (nvsvc) Display Driver Service Local Privilege Escalation',
'Description' => %q{
The named pipe, \pipe\nsvr, has a NULL DACL allowing any authenticated user to
interact with the service. It contains a stacked based buffer overflow as a result
of a memmove operation. Note the slight spelling differences: the executable is 'nvvsvc.exe',
the service name is 'nvsvc', and the named pipe is 'nsvr'.
This exploit automatically targets nvvsvc.exe versions dated Nov 3 2011, Aug 30 2012, and Dec 1 2012.
It has been tested on Windows 7 64-bit against nvvsvc.exe dated Dec 1 2012.
