Descriptions

net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a buffer overflow in the handling of the `INDEX` of `NET-SNMP-VACM-MIB` can cause an out-of-bounds memory access. A user with read-only credentials can exploit the issue. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. Those who must use SNMPv1 or SNMPv2c should use a complex community string and enhance the protection by restricting access to a given IP address range.

net-snmp proporciona varias herramientas relacionadas con el protocolo simple de administración de red. Antes de la versión 5.9.2, un desbordamiento del búfer en el manejo del `INDEX` de `NET-SNMP-VACM-MIB` puede provocar un acceso a la memoria fuera de los límites. Un usuario con credenciales de sólo lectura puede aprovechar el problema. La versión 5.9.2 contiene un parche. Los usuarios deben utilizar credenciales SNMPv3 seguras y evitar compartirlas. Aquellos que deben utilizar SNMPv1 o SNMPv2c deben utilizar una cadena de comunidad compleja y mejorar la protección restringiendo el acceso a un rango de direcciones IP determinado.
