--- title: "Security notices\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/notices?format=md keywords: index, follow --- # Ubuntu Security Notices Developers issue an Ubuntu Security Notice when a security issue is fixed in an [official Ubuntu package](https://packages.ubuntu.com). You can find additional guidance for high-profile vulnerabilities in the [Ubuntu Vulnerability Knowledge Base](https://ubuntu.com/security/vulnerabilities) section. To report a security vulnerability in an Ubuntu package, please [contact the Security Team](https://wiki.ubuntu.com/SecurityTeam/FAQ#Contact). The Security Team also produces [OVAL](https://ubuntu.com/security/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.
