The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6236-1 advisory.

    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.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5231 advisory.

  - An issue was discovered in the DNS proxy in Connman through 1.40. The TCP server reply implementation     lacks a check for the presence of sufficient Header Data, leading to an out-of-bounds read.
    (CVE-2022-23096)

  - An issue was discovered in the DNS proxy in Connman through 1.40. forward_dns_reply mishandles a strnlen     call, leading to an out-of-bounds read. (CVE-2022-23097)

  - An issue was discovered in the DNS proxy in Connman through 1.40. The TCP server reply implementation has     an infinite loop if no data is received. (CVE-2022-23098)

  - In ConnMan through 1.41, remote attackers able to send HTTP requests to the gweb component are able to     exploit a heap-based buffer overflow in received_data to execute code. (CVE-2022-32292)

  - In ConnMan through 1.41, a man-in-the-middle attack against a WISPR HTTP query could be used to trigger a     use-after-free in WISPR handling, leading to crashes or code execution. (CVE-2022-32293)
