US-CERT/NIST
Overview
OpenSSL 0.9.8c-1 up to versions before 0.9.8g-9 on Debian-based operating systems uses a random number generator that generates predictable numbers, which makes it easier for remote attackers to conduct brute force guessing attacks against cryptographic keys.
Impact
CVSS Severity (version 2.0):
Impact Subscore:
6.9
Exploitability Subscore:
10.0
CVSS Version 2 Metrics:
Access Vector: Network exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type:Allows unauthorized disclosure of information
- Official Statement from Red Hat (05/13/2008)
-
Not vulnerable. This flaw was caused by a third-party vendor patch to the OpenSSL
library. This patch has never been used by Red Hat, and this issue therefore does not affect any Fedora, Red Hat, or upstream supplied OpenSSL packages.
