CVE-2000-0535

MEDIUM
5.0NVD

Summary

generated automatically from NVD data

OpenSSL 0.9.4 and OpenSSH on FreeBSD fail to verify that the /dev/random or /dev/urandom devices exist, and these devices are missing on FreeBSD Alpha systems. As a result, cryptographic keys generated there are weak and may be easier to break. NVD lists FreeBSD 4.0 and 5.0 among the affected products and rates the flaw 5.0 (MEDIUM, CVSS v2.0), with the vector AV:N/AC:L/Au:N/C:N/I:P/A:N.

NVD description

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.
