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 security tracker page at:
https://security-tracker.debian.org/tracker/connman
