RealNetworks RealPlayer Shockwave Flash (SWF) file vulnerability

Vulnerability Note VU#298651

Original Release Date: 2008-07-28 | Last Revised: 2008-07-28


RealNetworks RealPlayer fails to properly handle frames within Shockwave Flash (SWF) files, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.


The RealNetworks RealPlayer application provides support for the SWF file format. A buffer overflow exists in the way that the RealPlayer handles specially crafted SWF files. A remote, unauthenticated attacker with the ability to supply a specially crafted SWF file could exploit this vulnerability to execute arbitrary code on an affected system.


By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user.
