Descriptions du CVE
Integer overflow in RealNetworks RealPlayer 8, 10, and 10.5, RealOne Player 1 and 2, and Helix Player 10.0.0 allows remote attackers to execute arbitrary code via an .rm movie file with a large value in the length field of the first data packet, which leads to a stack-based buffer overflow, a different vulnerability than CVE-2004-1481.

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.

RealNetworks RealPlayer and RealOne Player are reported prone to a remote stack-based buffer-overflow vulnerability. The applications fail to perform boundary checks when parsing RM (Real Media) files. A remote attacker may execute arbitrary code on a vulnerable computer to gain unauthorized access.
This vulnerability is reported to occur in RealNetworks products for Microsoft Windows, Linux, and Apple Mac platforms.

/* 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.
