CVE-2012-0950: Canonical Ubuntu Linux

Medium severity, CVSS 5.0. EPSS: 1.8% chance of exploitation in the next 30 days.

The Apport hook (DistUpgradeApport.py) in Update Manager, as used by Ubuntu 12.04 LTS, 11.10, and 11.04, uploads the /var/log/dist-upgrade directory when reporting bugs to Launchpad, which allows remote attackers to read repository credentials by viewing a public bug report. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0949.

Affected products

• Canonical Ubuntu Linux: version 11.04 only; version 11.10 only; version 12.04 only
