## Description

The js\_InitRandom function in the JavaScript implementation in Mozilla
Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, and SeaMonkey before
2.0.5, uses the current time for seeding of a random number generator,
which makes it easier for remote attackers to guess the seed value via a
brute-force attack, a different vulnerability than CVE-2008-5913.
