Security Vulnerability in Netscape 6.x and 7 With PNG Files

Category
Security

Release Phase
Workaround

Product
Solaris 7 Operating System

Bug Id
5089105

Date of Workaround Release
30-NOV-2004

Impact

Multiple security vulnerabilities have been discovered in the Portable Network Graphics (PNG) Library libpng(3) which also affect Netscape 6.x/7 shipped with Solaris since Netscape 6.x/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.
