Descriptions
NET-SNMP version 5.7.2 contains a heap corruption vulnerability in the UDP protocol handler that can result in command execution.
NET-SNMP 5.7.2 contiene una vulnerabilidad de corrupción de memoria dinámica (heap) en el manipulador del protocolo UDP que puede resultar en la ejecución de comandos.
It was discovered that the snmp_pdu_parse() mishandles error codes and is vulnerable to a heap corruption within the parsing of the PDU prior to the authentication process. A remote, unauthenticated attacker could use this flaw to crash snmpd or, potentially, execute arbitrary code on the system with the privileges of the user running snmpd.
