RealPlayer 10 beta, RealOne Player for Mac OS X affected by security issue

by CNET staff

eEye Digital Security says it discovered a critical vulnerability in RealPlayer. The vulnerability allows a remote attacker to reliably overwrite heap memory with arbitrary data and execute arbitrary code in the context of the user who executed the player.

A statement reads "This specific flaw exists within the pnen3260.dll file used by RealPlayer. By specially crafting a malformed .rm movie file along with a SMIL file, a direct heap overwrite is triggered, and reliable code execution is then possible."

In the case of Mac OS X, users only vulnerable if they play a local Real media file in either Real Player 10 Beta or RealOne Player.

RealNetworks has since released a patch for this vulnerability. The patch is available via the "Check for Update" menu item under the application menu (RealOne Player) in the menu bar. Real Player 10 (non-beta) is not affected by this issue.

    I have RealOne Player v. 9.0 When I tried getting the patch using the "Check for Update" I got message that software is up to date. No patch available. Also strange that they didn't advise me that RealPlayer 10 is available for download.

    Check For Updates, which is under "RealPlayer" (not "Tools") in the OS X
    menubar, tells me that my RealPlayer 10 is "up to date," no patch offered for
    download.

    According to the most recent Real security update
    document
    (http://service.real.com/help/faq/security/040928_player/
    EN/), RealPlayer 10 for Mac OS X appears to be
    unaffected by the vulnerabilities.

    The RealPlayer 10 Beta is subject to one of the three
    exploits described, however.

    RealPlayer 10 fixed UI oddities I had with www.bbc.co.uk/worldservice with Mozilla.
    But although it fixed some UI problems with www.couleur3.ch, it doesn't play anything there at all anymore (could also be a Java-related problem, i.e. changes on the site or with 1.4.2 Update 2).
