Descriptions

Netatalk through 3.1.13 has an afp_getappl heap-based buffer overflow resulting in code execution via a crafted .appl file. This provides remote root access on some platforms such as FreeBSD (used for TrueNAS).

Netatalk hasta 3.1.13 tiene un Desbordamiento del Búfer en afp_getappl que genera la ejecución de código a través de un archivo .appl manipulado. Esto proporciona acceso raíz remoto en algunas plataformas como FreeBSD (utilizado para TrueNAS).

This vulnerability allows remote attackers to bypass authentication on affected installations of Synology DiskStation Manager. This vulnerability does not require authentication, but does require some user interaction.
The specific flaw exists within the Serv.php endpoint. The issue results from incorrect implementation of the authentication mechanism. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root.
