Technical details
An integer underflow vulnerability exists in the dsi_writeinit() function within Netatalk's Data Stream Interface (DSI) handling. The flaw is caused by a missing bounds check that leads to a miscalculation of incoming payload sizes. An unauthenticated remote attacker can exploit this by sending specially crafted packets, forcing the 'afpd' process to spend excessive time receiving data, effectively causing a denial of service. While the issue does not lead to memory corruption or remote code execution, it can be triggered in pre-authentication protocol states. The vulnerability is fixed in version 4.4.3.
