CVE-2005-2946: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 0.8% chance of exploitation in the next 30 days.

The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature.

Affected products

• Canonical Ubuntu Linux: version 4.10 only; version 5.04 only
• OpenSSL OpenSSL: before 0.9.8 (fixed in 0.9.8)
