This issue allows remote attackers to execute arbitrary code on affected installations of Netatalk. Authentication is not required to exploit this issue. The specific flaw exists within the `dsi writeinit` function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this issue to execute code in the context of root.

A combinação de primitivas oferecidas pelo SMB e pelo AFP em sua configuração padrão permite a gravação arbitrária de arquivos. Ao explorar essa combinação de primitivas, um invasor pode executar código arbitrário.
