CVE-2026-44072 Details
Description
Netatalk 2.2.1 through 4.4.2 calls system() after a failed chdir() without properly handling the error condition, which allows a local privileged user to execute unintended commands or cause a minor service disruption under specific conditions.
A vulnerability exists in Netatalk versions 2.2.1 prior to 4.4.2, where the 'system()' function is called after a failed 'chdir()' operation. This issue can cause the CNID database cleanup process to inadvertently affect files in the wrong directory. Although the executed command is fixed and not subject to injection, the vulnerability could be exploited by manipulating the service environment to induce directory change failures.
Users can upgrade to Netatalk version 4.5.0 or later, which includes the necessary patch. Alternatively, the patch can be applied to a Netatalk 4.4.2 source tree. The Netatalk team advises against proactively applying the patch to existing deployments due to the low likelihood of exploitation.
