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
remote attacker could possibly use this issue to case ConnMan to crash,
resulting in a denial of service. This issue only affected Ubuntu 16.04
LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS.
(CVE-2022-23096, CVE-2022-23097)

It was discovered that ConnMan could be made to run into an infinite loop.
A remote attacker could possibly use this issue to cause ConnMan to
consume resources and to stop operating, resulting in a denial of service.

cause ConnMan to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu
18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-32292)

It was discovered that ConnMan did not properly manage memory under
certain circumstances. 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 16.04 LTS, Ubuntu
18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-32293)
