CVE-2008-1672: Canonical Ubuntu Linux

Medium severity, CVSS 4.3. EPSS: 5% chance of exploitation in the next 30 days.

OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service (crash) via a TLS handshake that omits the Server Key Exchange message and uses "particular cipher suites," which triggers a NULL pointer dereference.

Affected products

• Canonical Ubuntu Linux: version 8.04 only
• OpenSSL OpenSSL: version 0.9.8f only; version 0.9.8g only
