Multiple Security Vulnerabilities in Solaris 10 Firefox and Thunderbird

1. Impact

Multiple security vulnerabilities in the firefox(1) and thunderbird(1) applications shipped with Solaris 10 may allow a local or remote unprivileged user to execute arbitrary code on a remote machine with the privileges of a local user, cause firefox(1) and thunderbird(1) applications to crash, or conduct Cross-Site Scripting (XSS) attacks on sites which allow users to upload pictures, archives, or other files. The ability to crash the firefox(1) or thunderbird(1) application is a type of Denial of Service (DoS).

The following Mozilla advisories describe the vulnerabilities:


Additional references:


The issues described in mfsa2007-37, mfsa2007-38 and mfsa2007-39 affect Firefox only and are fixed in the Firefox patches listed in this Sun Alert.

The following additional issue described in MFSA2007-29 impacts both Firefox and Thunderbird, but is described for Firefox in Sun Alert 201516 (previously 103177), and is described for Thunderbird in this Sun Alert. It is fixed in the Thunderbird patches listed in this Sun Alert.

2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform

• Firefox 2.0 (for Solaris 10) without patch 125539-02
  
• Thunderbird 2.0 (for Solaris 10) without patch 125541-02
  

x86 Platform

• Firefox 2.0 (for Solaris 10) without patch 125540-03
  
• Thunderbird 2.0 (for Solaris 10) without patch 125542-02
  

Note: Solaris 8 and Solaris 9 do not ship Firefox and Thunderbird, and therefore are not affected by these issues.

Note: Firefox and Thunderbird first shipped with Solaris 10 Update 4 (8/07). Firefox is shipped in the SUNWfirefox package and Thunderbird is shipped in the SUNWthunderbird package.

To determine which update release has been installed on a Solaris 10 system, review the /etc/release file:

    $ cat /etc/release
                 Solaris 10 8/07 s10s_u4wos_12b SPARC

                   Assembled 16 August 2007

3. Symptoms

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

4. Workaround

To work around the issues described in CVE-2007-5947, sites can use a proxy server or application firewall which blocks URIs that contain jar: URIs.
