The following Mozilla advisories describe the vulnerabilities: http://www.mozilla.org/security/announce/2007/mfsa2007-18.html http://www.mozilla.org/security/announce/2007/mfsa2007-19.html http://www.mozilla.org/security/announce/2007/mfsa2007-20.html http://www.mozilla.org/security/announce/2007/mfsa2007-21.html http://www.mozilla.org/security/announce/2007/mfsa2007-22.html http://www.mozilla.org/security/announce/2007/mfsa2007-24.html http://www.mozilla.org/security/announce/2007/mfsa2007-25.html http://www.mozilla.org/security/announce/2007/mfsa2007-26.html http://www.mozilla.org/security/announce/2007/mfsa2007-27.html http://www.mozilla.org/security/announce/2007/mfsa2007-28.html http://www.mozilla.org/security/announce/2007/mfsa2007-29.html http://www.mozilla.org/security/announce/2007/mfsa2007-30.html http://www.mozilla.org/security/announce/2007/mfsa2007-31.html http://www.mozilla.org/security/announce/2007/mfsa2007-32.html http://www.mozilla.org/security/announce/2007/mfsa2007-33.html http://www.mozilla.org/security/announce/2007/mfsa2007-34.html http://www.mozilla.org/security/announce/2007/mfsa2007-35.html Additional references: CERT Technical Cyber Security Alert TA07-199A at http://www.us-cert.gov/cas/techalerts/TA07-199A.html US-CERT VU#143297 at http://www.kb.cert.org/vuls/id/143297 US-CERT VU#783400 at http://www.kb.cert.org/vuls/id/783400 US-CERT VU#403150 at http://www.kb.cert.org/vuls/id/403150 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 125540-02 * 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. 3. Symptoms There are no predictable symptoms that would indicate the described issues have been exploited. 4. Workaround A) To work around the issues described in MFSA-2007-20, disable JavaScript by doing the following: 1. Open the "Preferences" dialog from the Edit menu 2. Select the "Content" tab 3. Uncheck the "Enable JavaScript" check box B) The workaround for MFSA-2007-26 would depend on the "add-on" in question. The workaround for Web Developer Toolbar add-on is to use it in its default configuration. Other affected add-ons might not have a workaround other than to upgrade to a fixed version of Firefox. C) To work around the issues described in MFSA-2007-27, force mail-related links to prompt in Firefox before launching external programs by doing the following: 1. Enter 'about:config' in the location bar 2. Enter 'warn-external' in the Filter: box 3. Double-click to set the mailto, news, nntp and snews lines to 'true'. Note: CVE-2007-3089 = MFSA-2007-20 CVE-2007-3844 = MFSA-2007-26 CVE-2007-3845 = MFSA-2007-27 5.
