UBUNTU SECURITY NOTICES

Developers issue an Ubuntu Security Notice when a security issue is fixed in an
official Ubuntu package.

To report a security vulnerability in an Ubuntu package, please contact the
Security Team.

The Security Team also produces OVAL files for each Ubuntu release. These are an
industry-standard machine-readable format dataset that contain details of all
known security vulnerabilities and fixes relevant to the Ubuntu release, and can
be used to determine whether a particular patch is appropriate. OVAL files can
also be used to audit a system to check whether the latest security fixes have
been applied.
