Descriptions

Netatalk before 3.1.12 is vulnerable to an out of bounds write in dsi_opensess.c. This is due to lack of bounds checking on attacker controlled data. A remote unauthenticated attacker can leverage this vulnerability to achieve arbitrary code execution.

Netatalk, en versiones anteriores a la 3.1.12, es vulnerable a una escritura fuera de límites en dsi_opensess.c. Esto se debe a la falta de comprobación de límites de los datos controlados por el atacante. Un atacante remoto no autenticado puede aprovechar esta vulnerabilidad para lograr la ejecución de código arbitrario.

QNAP Netatalk versions prior to 3.1.12 suffer from an authentication bypass vulnerability.
