Bug#945332: libsystemd0: sd-event leaks file descriptors

[Matthijs van Duin]

Package: libsystemd0
Version: 241-7~deb10u2
Severity: normal

When an sd-event io event source with fd ownership is released while it
is dispatching (i.e. from inside the event callback), the event source
is freed after dispatching is complete but it fails to close the fd.

This bug has recently been fixed upstream:
