* Sun Alert ID: 57683
* Synopsis: Security Vulnerability in Netscape 7 With PNG Files

* Product: Solaris, Netscape

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.
