Name of the Vulnerable Software and Affected Versions: xen (affected versions not specified)

Description: A recent systemd update caused a regression in 'xenstored.service', where systemd now fails to track units that use systemd-notify. The issue is resolved by adding a fix to delay between the call to 'systemd-notify' and the final exit of the wrapper script, and by running xenstored in a separate process to make it more robust for large and/or concurrent batches of xenstore accesses.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
