Name of the Vulnerable Software and Affected Versions Swift versions prior to 4.1.1 Security Update 2018-001

Description The issue involves the "Swift for Ubuntu" component and allows attackers to execute arbitrary code in a privileged context. This is possible because write and execute permissions are enabled during library loading.

Recommendations For versions prior to 4.1.1 Security Update 2018-001, update to Swift 4.1.1 Security Update 2018-001 to resolve the issue. As a temporary workaround, consider restricting the use of the "Swift for Ubuntu" component until the update is applied.
