Mandriva Linux Security Advisory 2015-008 - Pwgen was found to generate weak non-tty passwords by default, which could be brute-forced with a commendable success rate, which could raise security concerns. Pwgen was found to silently falling back to use standard pseudo generated numbers on the systems that heavily use entropy. Systems, such as those with a lot of daemons providing encryption services, the entropy was found to be exhausted, which forces pwgen to fall back to use standard pseudo generated numbers.
