A flaw was found in zulucrypt. Misconfigured PolicyKit allows settings within the CMakeLists.txt file to permit a local user to elevate their privileges to root. This insecure configuration bypasses authorization checks, allowing unauthorized actions. The vulnerability is triggered by the PolicyKit authorization process itself, requiring no external input. Consequently, a local attacker can gain root access without authentication. Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
