Updated pwgen package fixes security vulnerabilities:
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 (CVE-2013-4440).
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 (CVE-2013-4442).
