CVE-2013-2037: Canonical Ubuntu Linux

Low severity, CVSS 2.6. EPSS: 1.3% chance of exploitation in the next 30 days.

httplib2 0.7.2, 0.8, and earlier, after an initial connection is made, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Affected products

• Canonical Ubuntu Linux: version 10.04 only; version 12.04 only; version 12.10 only; version 13.04 only
• HTTPLIB2 Project HTTPLIB2: up to and including 0.7.2; version 0.8 only
