Multiple vulnerabilities have been reported in Mozilla Firefox.

2.  Impact Information


Mozilla Firefox is a popular open-source web browser from the Mozilla Project.


Mozilla Firefox improperly handles Script objects while they are being executed. Mozilla Firefox has also been found to be vulnerable to various possible buffer overflows. Lastly, the binary release of Mozilla Firefox is vulnerable to a low exponent RSA signature forgery issue because it is bundled with a vulnerable version of NSS.


An attacker could entice a user to view specially crafted JavaScript and execute arbitrary code with the rights of the user running Mozilla Firefox. An attacker could also entice a user to view a specially crafted web page that causes a buffer overflow and again executes arbitrary code. It is also possible for an attacker to make up SSL/TLS certificates that would not be detected as invalid by the binary release of Mozilla Firefox, raising the possibility for Man-in-the-Middle attacks.

3.  Resolution Information


There is no known workaround at this time.


All Mozilla Firefox users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-"

All Mozilla Firefox binary release users should upgrade to the latest version:

Code Listing 3.2: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-"
