by now you likely have heard about the debian openssl vulnerability found by luciano bello. it was originally announced on may 13th. what occurred is that code was removed because it caused the valgrind and purify tools to produce warnings about the use of uninitialized data in code that was linked to openssl. this change caused only the current process id to be used for the initial seed crippl...

ive ranted about this at length before im sure even in print in oreilys open sources 2. but now debian have proved me right again beyond my wildest expectations. two years ago they fixed a problem in openssl reported by valgrind1 by removing any possibility of adding any entropy to openssls pool of randomness2. the result of this is that for the last two years from debians etch release until now ...
