The layout engine in Mozilla Firefox before 4.0, Thunderbird before 3.3,
and SeaMonkey before 2.1 executes different code for visited and unvisited
links during the processing of Cascading Style Sheets (CSS) token
sequences, which makes it easier for remote attackers to obtain sensitive
information about visited web pages via a timing attack.
