That nemesis of application security, the buffer overrun, has found its way into media players from RealNetworks.
Three similar, though separate, flaws in RealPlayer (and its update RealOne) create a way for crackers to inject hostile code onto Windows boxes of victims induced to run maliciously constructed media files.
In common with most buffer overflow flaws (which are typically attributable to programming errors), hostile code could execute in the security context of the logged-on user/victim.
All three flaws were discovered by NGS Software. It notified RealNetworks of the problem on November 1, and the company followed up with an advisory and security fixes on November 20.
Problem is - the fixes dont work.
Mark Litchfield, of NGS Software, found that patches failed to address the problem.
