In short

A buffer overflow in SNMP allows authenticated attackers to crash the system or execute malicious code by sending specially crafted SNMP packets. This is dangerous because it can give attackers complete control over the device.

Buffer overflow vulnerability in SNMP implementation (versions 1, 2c, 3) triggered by crafted SNMP packets sent to the affected device. Requires valid SNMP credentials (community string for v1/2c or user credentials for v3) and network access to the target; successful exploitation results in arbitrary code execution or system reload (CVSS 8.8).

A vulnerability in the SNMP implementation of could allow an authenticated, remote attacker to cause a reload of the affected system or to remotely execute code. An attacker could exploit this vulnerability by sending a crafted SNMP packet to the affected device.  The vulnerability is due to a buffer overflow in the affected code area. The vulnerability affects all versions of SNMP (versions 1, 2c, and 3). The attacker must know the SNMP read only community string (SNMP version 2c or earlier) or the user credentials (SNMPv3).
