CVE-2026-44064 Details
Description
An out-of-bounds read in ASP session ID handling in Netatalk 1.3 through 4.4.2 allows an adjacent network attacker to obtain limited information or cause a denial of service via a crafted ASP request.
A vulnerability allowing out-of-bounds access has been identified in Netatalk versions 1.3 through 4.4.2. This issue arises from legacy ASP/DDP session management, where an attacker-controlled session identifier is used as an array index without proper validation against the session table size. As a result, an unauthenticated network attacker could potentially crash the service. While reliable code execution is less certain, the possibility exists.
Users can upgrade to Netatalk version 4.4.3 or later, which includes the necessary patch. Alternatively, the patch can be applied to a Netatalk 4.4.2 source tree. Netatalk administrators are advised to take action as soon as possible.
