"A remote information leak vulnerability and a remote buffer overflow
vulnerability were discovered in ConnMan, a network manager for
embedded devices, which could result in denial of service or the
execution of arbitrary code.

For Debian 9 stretch, these problems have been fixed in version
1.33-3+deb9u2.

We recommend that you upgrade your connman packages.

For the detailed security status of connman please refer to its
