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 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. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-23098)

It was discovered that ConnMan could be made to write out of bounds via the gweb component. 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-2022-32292)

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)

It was discovered that ConnMan could be made to write out of bounds via the gdhcp component. A remote attacker could possibly use this issue to cause ConnMan to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-28488)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected connman, connman-dev and / or connman-vpn packages.
