Stay informed of any changes for a specific CVE.
CVE Descriptions
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 is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

/*
source: https://www.securityfocus.com/bid/15381/info
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.
