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.

Affected products

Mozilla Firefox: 3.5, 3.5.1, 3.5.2, 3.5.3, 3.5.4, 3.5.5 (+7)
Mozilla Seamonkey: through 2.0.4; 1.0, 1.0-alpha, 1.0-beta, 1.0.1, 1.0.2, 1.0.3 (+37)
