Descriptions

Mozilla Firefox before 3.0.7, Thunderbird before 2.0.0.21, and SeaMonkey before 1.1.15 decode invisible characters when they are displayed in the location bar, which causes an incorrect address to be displayed and makes it easier for remote attackers to spoof URLs and conduct phishing attacks.

Mozilla Firefox en versiones anteriores a 3.0.7, Thunderbird en versiones anteriores 2.0.0.21 y SeaMonkey en versiones anteriores a 1.1.15, decodifican caracteres invisibles cuando son desplegados en la barra de ubicación, lo que causa que se muestre una dirección incorrecta y hace más fácil para los atacantes remotos falsificar URL y realizar ataques de phishing.

Security vulnerabilities have been discovered and corrected in the latest Mozilla Firefox 3.x, version 3.0.7. This update provides the latest Mozilla Firefox 3.x to correct these issues. As Mozilla Firefox 2.x has been phased out, version 3.x is also being provided for Mandriva Linux 2008 Spring. Additionally some software has also been rebuilt against Mozilla Firefox 3.0.7 which should take care of upgrade problems.
