New netscape packages are availabe to fix a problem with the handling of JavaScript in certain situations. By exploiting this flaw, a remote site could gain access to the browser history, and possibly other data. It is recommended that all users upgrade to the fixed packages. 2001-04-16: netscape-4.77-1 packages are now available for Red Hat Linux 7.1 for Intel.
Netscape does not escape GIF file comments in the image information page; this allows JavaScript commands embedded therein to be executed. These commands could access data such as the browser history. Credit goes to Florian Wesch <fw@divduum.de> for discovering the vulnerability, and to Netscape for providing fixed packages.
