Package        : systemd
Version        : 232-25+deb9u14
CVE ID         : CVE-2020-1712
Debian Bug     : 950732

A heap use-after-free vulnerability was found in systemd, a system and
service manager, where asynchronous Polkit queries are performed while
handling dbus messages. A local unprivileged attacker can abuse this
flaw to crash systemd services or potentially execute code and elevate
their privileges, by sending specially crafted dbus messages.

For Debian 9 stretch, this problem has been fixed in version
232-25+deb9u14.

We recommend that you upgrade your systemd packages.
