    Sun(sm) Alert Notification
      * Sun Alert ID: 57683
      * Synopsis: Security Vulnerability in Netscape 7 With PNG Files
      * Category: Security
      * Product: Solaris, Netscape
      * BugIDs: 5089105
      * Avoidance: Upgrade
      * State: Engineering Complete
      * Date Released: 30-Nov-2004
      * Date Closed:
      * Date Modified:

    1. Impact Multiple security vulnerabilities have been discovered in
    the Portable Network Graphics (PNG) Library libpng(3) which also
    affect Netscape 7 shipped with Solaris since Netscape 7 includes the
    affected libpng routines. This may allow an unprivileged user to
    execute arbitrary code with the privileges of a local user. This
    condition can be exploited when the local user has loaded a Portable
    Network Graphics (PNG) format image file supplied by an untrusted user
    and views a malicious web site or views an e-mail message containing a
    malformed PNG image with that application.

    Note: Netscape is utilized as web browser and editor, an irc client,
    an email client, and a news client.

    7, 8 and 9 (part of the SUNWnsb package).

    To determine the version of Netscape 7 installed on a system, the
    following command can be run:

     $ pkginfo -l SUNWnsb | grep VERSION

    To determine which Solaris 9 Update release is installed on the system
    check the contents of the "/etc/release" file:
