Debian's OpenSSL Library Predictable Random Number Generator

Severity CVSS Published Added Modified
8 (AV:N/AC:L/Au:N/C:C/I:N/A:N) May 13, 2008 June 05, 2008 February 13, 2015


A weakness has been discovered in the random number generator used by OpenSSL on Debian and Ubuntu systems. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledge of the system. This particularly affects the use of encryption keys in OpenSSH, OpenVPN and SSL certificates. This vulnerability only affects operating systems which are based on Debian. However, other systems can be indirectly affected if weak keys are imported into them.
