CVE-2026-44069 Details
Description
An integer underflow in the volxlate function in Netatalk 3.0.0 through 4.4.2 allows a local privileged user to obtain limited information, modify limited data, or cause a minor service disruption via crafted volume translation input.
An integer underflow vulnerability has been identified in Netatalk versions 3.0.0 through 4.4.2, specifically within the 'volxlate' component responsible for path translation. The issue arises because the component subtracts the length of formatted output from the available destination buffer size without proper validation, leading to potential mishandling of buffer accounting. While this vulnerability has a low practical exploitability—since high-risk inputs are typically controlled by administrators or are otherwise limited—it's important to address it.
Users can upgrade to Netatalk version 4.5.0 or later, which includes the necessary patch. Alternatively, the patch can be applied manually to a Netatalk 4.4.2 source tree. The Netatalk team advises against proactively applying the patch to existing deployments due to the low risk of exploitation.
