Subject: CVE Request -- perl-Crypt-DSA -- Cryptographically insecure method
 used for random numbers generation on systems without /dev/random

Hello Josh, Steve, vendors,

   it has been reported that Crypt::DSA, a Perl module for DSA
signatures and key generation, used cryptographically weak / insecure
method for random numbers generation on systems, where /dev/random file
was not present. Due this flaw an attacker could be able to discover
some portions of / whole secret DSA key, which has been created on such


Proposed upstream patch is to remove the affected fallback code part:

Could you allocate a CVE id for this?

Thank you && Regards, Jan.
