CVE-2011-4405: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 3.4% chance of exploitation in the next 30 days.

The cupshelpers scripts in system-config-printer in Ubuntu 11.04 and 11.10, as used by the automatic printer driver download service, uses an "insecure connection" for queries to the OpenPrinting database, which allows remote attackers to execute arbitrary code via a man-in-the-middle (MITM) attack that modifies packages or repositories.

Affected products

• Canonical Ubuntu Linux: version 11.04 only; version 11.10 only
