Description Mark J. Cox 2003-10-31 14:15:18 UTC 
Perl 5.8.1 (only) has bad random number initialisation when
forking leading to predictive random numbers, which is bad
for mod_perl and other things. 

Only affects Fedora Core as we haven't shipped 5.8.1 in other distributions.
Comment 1 Chip Turner 2003-10-31 14:41:40 UTC 
the 5.8.1 in fedora core 1 is patched against this

perl -le 'fork; print rand'

prints different numbers in fedora, but not stock 5.8.1

Looks like it is patched in FC1 and does not affect other releases.
Comment 3 Mark J. Cox 2003-11-07 09:11:55 UTC 
agreed
