Stay informed of any changes for a specific CVE.
CVE Descriptions
Stack-based buffer overflow in the Database Component in MPAMedia.dll in RealNetworks RealPlayer 10.5 and 11 beta, and earlier versions including 10, RealOne Player, and RealOne Player 2, allows remote attackers to execute arbitrary code via certain playlist names, as demonstrated via the import method to the IERPCtl ActiveX control in ierpplug.dll.
CVE Informations
Related Weaknesses
| Weakness Name | Source | |
|---|---|---|
| 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 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.

This module exploits a stack buffer overflow in RealOne Player V2 Gold Build 6.0.11.853 and
RealPlayer 10.5 Build 6.0.12.1483. By sending an overly long string to the "Import()"
method, an attacker may be able to execute arbitrary code.

RealPlayer is prone to a stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks of user-supplied input before copying it to an insufficiently sized memory buffer.
Attackers can exploit this issue to execute arbitrary code in the context of the application using the affected control (typically Internet Explorer). Successful attacks can compromise the application and possibly the underlying computer. Failed attacks will likely cause denial-of-service conditions.
