-- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of RealNetworks RealPlayer. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page or open a malicious file.

The specific flaw exists when parsing a RealMedia .IVR file containing
malformed sample data. The application utilizes a index in this data
stream for seeking into a list of objects. Due to the lack of
constraints on this index, one can seek to an arbitrary object located
in memory which will lead to code execution under the context of the
currently logged in user.

-- Vendor Response:
RealNetworks has issued an update to correct this vulnerability. More
