Multiple Security Vulnerabilities in Firefox Versions Prior to 3.5.2 May Allow Execution of Arbitrary Code or Application Crash

1. Impact

Multiple security vulnerabilities with varying impacts affect Firefox (see firefox(1)) versions prior to 3.5.2 as shipped with OpenSolaris. These vulnerabilities may allow an unprivileged remote user to execute arbitrary code on the system where Firefox is being run or to crash the Firefox application which is a type of Denial of Service (DoS).

The following URL provides additional details about the vulnerabilities addressed in Firefox versions 3.5.1 and 3.5.2:


The following Mozilla advisories describe the vulnerabilities:


The following are the CVE identifiers that pertain to this security issue:


2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• OpenSolaris builds snv_119 through snv_121

x86 Platform

• OpenSolaris builds snv_119 through snv_121

Notes:

1. Solaris 8 and 9 do not include Firefox and therefore are not impacted by these issues.

2. Solaris 10 does not currently include Firefox 3.x and OpenSolaris prior to snv_95 does not include Firefox 3.x.

3. The 2.x version of Firefox currently shipped in Solaris 10 may be affected by these issues 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_119

3. Symptoms

There are no predictable symptoms that would indicate the described issue has occurred.

4. Workaround

Until firefox can be updated users of Firefox 3.5 can avoid the exploitable memory corruption issue related to the Just-in-Time (JIT) compiler by disabling the JIT compiler as described in the Mozilla Security Blog at:


MFSA 2009-45 can be worked around by disabling JavaScript by following the steps below:


5. Resolution

This issue is addressed in the following releases:

SPARC Platform

• OpenSolaris build snv_122 or later

x86 Platform
