NVD Description

Note: Versions mentioned in the description apply only to the upstream netatalk package and not the netatalk package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Synology DiskStation Manager. Authentication is not required to exploit this vulnerablity. The specific flaw exists within the processing of DSI structures in Netatalk. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12326.
