TITLE

Intel's  connman  Vulnerability related to use of freed memory in products from other vendors

DESCRIPTION

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. Intel's connman Products from multiple other vendors contain vulnerabilities related to use of freed memory.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ConnMan. Authentication is not required to exploit this vulnerability.The specific flaw exists within the wispr_portal_web_result method. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to execute code in the context of the ConnMan process. This vulnerability was demonstrated on a Tesla Model 3 during Pwn2Own 2022 Vancouver competition. For the stable distribution (bullseye), these problems have been fixed in version 1.36-2.2+deb11u1. We recommend that you upgrade your connman packages.

Software Description: - connman: Intel Connection Manager daemon Details: 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) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 23.04: connman 1.41-2ubuntu0.23.04.1 Ubuntu 22.04 LTS: connman 1.36-2.3ubuntu0.1 Ubuntu 20.04 LTS: connman 1.36-2ubuntu0.1 Ubuntu 18.04 LTS (Available with Ubuntu Pro): connman 1.35-6ubuntu0.1~esm1 Ubuntu 16.04 LTS (Available with Ubuntu Pro): connman 1.21-1.2+deb8u1ubuntu0.1~esm1 In general, a standard system update will make all the necessary changes.
