CVE-2022-1804:
Linux Ubuntu vulnerability analysis and mitigation
Overview
AccountsService vulnerability (CVE-2022-1804) was discovered on May 19, 2022, affecting the accountsservice package in Ubuntu 22.04 LTS. The vulnerability occurs when accountsservice no longer drops permissions when writing .pam_environment file. This issue was originally addressed as CVE-2020-16126 but was accidentally reverted in version 0.6.55-3ubuntu1 (Ubuntu Security, NVD).
Technical details
The vulnerability is related to improper privilege management (CWE-269) where accountsservice fails to properly drop privileges when writing to .pam_environment. The issue has a CVSS v3.1 Base Score of 5.5 (Medium) with vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, indicating local access required with low attack complexity (NVD).
Impact
When exploited, this vulnerability could allow a local user to cause AccountsService to crash or stop responding, resulting in a denial of service. Additionally, the vulnerability causes ~/.pam_environment files to be created with root ownership instead of the current user's ownership (Ubuntu Security Notice).
Mitigation and workarounds
The vulnerability was fixed in Ubuntu 22.04 LTS with accountsservice version 22.07.5-2ubuntu1.3. The fix includes updating the language-tools patch to not reset effective uid and migrate root-owned .pam_environment files. Users are advised to update their systems to the patched version and perform a system reboot to apply all necessary changes (Ubuntu Security Notice).
