Multiple Security Vulnerabilities in Firefox Versions Prior to 3.5b4 May Allow Execution of Arbitrary Code or Access to Unauthorized Data

1. Impact

Multiple security vulnerabilities with varying impacts affect Firefox (see firefox(1)) versions prior to 3.5b4 as shipped with OpenSolaris. These vulnerabilities may allow an unprivileged remote user to execute arbitrary code on the system where Firefox is being run, cause a Denial of Service (DoS) crash to the Firefox application, gain unauthorized access to sensitive data, execute arbitrary scripting code within a user's browsing session via Cross-Site Scripting (XSS) exploits to read or modify data from other web sites, obtain sensitive data from the user or information stored in cookies, or to perform Cross-Site Request Forgery (CSRF) attacks.

Additional vulnerabilities may allow a remote user to mislead a Firefox user into incorrectly trusting a site by providing a URL in the location bar which may appear to be another URL, or to bypass various security policies that are active in the browser to perform unauthorized activities such as reading local files or initiating network connections.

The following URL provides additional details about the vulnerabilities addressed in Firefox versions prior to 3.5b4.

2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform

• OpenSolaris based upon builds snv_95 through snv_114

x86 Platform

• OpenSolaris based upon builds snv_95 through snv_114

Note: Solaris 8 and 9 do not include Firefox and therefore are not impacted by these issues. Solaris 10 and OpenSolaris prior to snv_95 do not ship Firefox 3.x, but the Firefox version 2.x that is included may be impacted, in which case a separate Sun Alert describing the resolution for Solaris 10 will be published.
     
OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. The base build can be derived as follows:

$ uname -v
snv_95

3. Symptoms

There are no predictable symptoms that would indicate the described issues have occurred.
