The Linux implementation of the ICMP-MIB in Net-SNMP 5.5 before 5.5.2.1, 5.6.x before 5.6.2.1, and 5.7.x before 5.7.2.1 does not properly validate input, which allows remote attackers to cause a denial of service via unspecified vectors.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
