Fedora 18 : perl-Crypt-DSA-1.17-10.fc18 (2013-15755)

As taught by the '09 Debian PGP disaster relating to DSA, the randomness source is extremely important. On systems without /dev/random, Crypt::DSA falls back to using Data::Random. Data::Random uses rand, about which the perldoc says 'rand is not cryptographically secure. You should not rely on i...

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2007-0376 advisory. 2.6.18-8.1.6.0.1.el5 -Fix bonding primary=ethX so it picks correct network Bert Barbe IT 101532 ORA 5136660 -Add entropy module option to e1000 John...

CVE-2011-3599

The Crypt::DSA aka Crypt-DSA module 1.17 and earlier for Perl, when /dev/random is absent, uses the Data::Random module, which makes it easier for remote attackers to spoof a signature, or determine the signing key of a signed message, via a brute-force attack...

CVE-2003-0094

CVE-2003-0094 affects Mandrake Linux 8.2/9.0 util-linux mcookie. The patch changed the entropy source from /dev/random to /dev/urandom, making mcookie output more predictable and potentially aiding certain attacks. The Nessus advisory notes the patch was removed in these updates, restoring a bett...

CVE-2000-0535

CVE-2000-0535 affects OpenSSL 0.9.4 and OpenSSH on FreeBSD, where FreeBSD Alpha's missing /dev/random or /dev/urandom leads to weak cryptographic keys. The issue arises from improper device checks, resulting in keys that may be easier to break. The provided documents describe the root cause and a...

CVE-2000-0535: Undefined Security Weakness

OpenSSL 0.9.4 and OpenSSH for FreeBSD do not properly check for the existence of the /dev/random or /dev/urandom devices, which are absent on FreeBSD Alpha systems, which causes them to produce weak keys which may be more easily broken...

Проблемы с /dev/random в FreeBSD на alpha

В версии FreeBSD для платформы alpha отсутствовало устройство /dev/random генерирующее псевдо-случайные последовательности. Тем не менее, многие крипто-программы, включая OpenSSH и OpenSSL генерировали ключи и сертификаты не учитывая этот факт...
