Firefox 3.5.1 Released
alek writes "A day after Slashdot reports about a self-inflicted vulnerability in Firefox 3.5, Mozilla releases 3.5.1. It addresses that security issue, but also fixes the annoying slow-startup on Windows. Bummer the UNIX wars have subsided, because apparently they also had to fix a problem where Firefox on a Sparc platform would crash when visiting www.hp.com!"
On further study, it NSS DOES use process IDs and many, many other factors to generate the seeds. Searching the additional file locations ("C:\Documents and Settings\*user*\Local Settings\History", "C:\Documents and Settings\*user*\Local Settings\Temporary Internet Files", "C:\Documents and Settings\*user*\My Recent Documents", "C:\Documents and Settings\*user*\Temp\", "Recycle Bin", and "Network Neighborhood") were added because some older OSs (Win2k and WinCE) didn't have strong enough build-in pseudo-random number generators.
This patch changed NSS to use the built-in PRNG in Windows XP and up which uses "process ID and thread ID, the system clock, the system time, the system counter, memory status, free disk clusters, andthe hashed user environment block".
