Descriptions du CVE
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.

| Nom de la faiblesse | 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. |

EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
Percentile EPSS
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres 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.
