Descriptions du CVE
An ActiveX control in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.4, and RealPlayer Enterprise 2.1.2 does not properly initialize an unspecified object component during parsing of a CDDA URI, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized pointer dereference and application crash) via a long URI.

|---|---|---|
| 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' => 'RealNetworks RealPlayer CDDA URI Initialization Vulnerability',
'Description' => %q{
This module exploits a initialization flaw within RealPlayer 11/11.1 and
RealPlayer SP 1.0 - 1.1.4. An abnormally long CDDA URI causes an object
initialization failure. However, this failure is improperly handled and
uninitialized memory executed.
