Notifications for a CVE
Stay informed of any changes for a specific CVE.
CVE Descriptions
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.
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. |
Metrics

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.

'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.
