CVE-2026-44071 Details
Description
Netatalk 3.1.2 through 4.4.2 is compiled without FORTIFY_SOURCE, which disables built-in buffer overflow detection at runtime, potentially allowing a remote attacker to cause a minor denial of service via memory errors that would otherwise be caught and safely terminated by runtime protection.
A denial-of-service vulnerability has been identified in Netatalk versions 3.1.2 prior to 4.4.2. The issue arises because the software is compiled without FORTIFY_SOURCE, which disables built-in buffer overflow detection at runtime. This omission could allow a remote attacker to cause memory errors, leading to a minor denial-of-service condition, as these errors would typically be caught and safely terminated by the runtime protection.
Users can apply the CVE-2026-44071.patch to a Netatalk 4.4.2 source tree to hotfix their local Netatalk deployment. Alternatively, upgrading to Netatalk 4.5.0 or later, which includes the patch, is recommended. However, the Netatalk team does not encourage proactively applying the patch to existing deployments due to the low practical exploitability.
