Doc Text:
A flaw was found in perl-Crypt-DSA. This vulnerability occurs because the software generates cryptographic seeds using Perl's built-in `rand` function, which is predictable and unsuitable for security-sensitive operations. An attacker could potentially leverage this predictability to weaken the cryptographic security of generated keys, leading to potential information disclosure or other security bypasses.

Description OSIDB Bzimport 2026-05-15 23:01:24 UTC 
Crypt::DSA versions before 1.20 for Perl generate seeds using rand.

Seeds were generated using Perl's built-in rand function, which is predictable and unsuitable for security usage.
