Package        : systemd

The Qualys Research Labs reported that the backported security fixes
shipped in DSA 4367-1 contained a memory leak in systemd-journald. This
and an unrelated bug in systemd-coredump are corrected in this update.

Note that as the systemd-journald service is not restarted automatically
a restart of the service or more safely a reboot is advised.

For the stable distribution (stretch), these problems have been fixed in
version 232-25+deb9u8.

We recommend that you upgrade your systemd packages.

For the detailed security status of systemd please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/systemd

CVE ID         : CVE-2018-16864 CVE-2018-16865 CVE-2018-16866
Debian Bug     : 918841 918848

The Qualys Research Labs discovered multiple vulnerabilities in
systemd-journald. Two memory corruption flaws, via attacker-controlled
alloca()s (CVE-2018-16864, CVE-2018-16865) and an out-of-bounds read flaw
leading to an information leak (CVE-2018-16866), could allow an attacker to
cause a denial of service or the execution of arbitrary code.
