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.
