Synopsis
========

RealPlayer is vulnerable to a heap overflow that could lead to remote
execution of arbitrary code.

Background
==========

RealPlayer is a multimedia player capable of handling multiple
multimedia file formats.

  1  media-video/realplayer      < 10.0.5                    >= 10.0.5

Description
===========

RealPlayer is vulnerable to a heap overflow when opening RealMedia
files which make use of RealText.

Impact

attacker could execute arbitrary code with the permissions of the user
running the application.

Workaround
