Summary
It was discovered that ConnMan could be made to write out of bounds. A
remote attacker could possibly use this issue to cause ConnMan to crash,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
(CVE-2021-26675, CVE-2021-33833)
It was discovered that ConnMan could be made to leak sensitive information
via the gdhcp component. A remote attacker could possibly use this issue
to obtain information for further exploitation. This issue only affected
Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2021-26676)
It was discovered that ConnMan could be made to read out of bounds. A
