A Denial of Service vulnerability has been discovered in Net-SNMP when processing GETBULK requests.
|Package||net-analyzer/net-snmp on all architectures|
|Affected versions||< 5.4.1-r1|
|Unaffected versions||>= 5.4.1-r1|
Net-SNMP is a collection of tools for generating and retrieving SNMP data.
The SNMP agent (snmpd) does not properly handle GETBULK requests with an overly large "max-repetitions" field.
A remote unauthenticated attacker could send a specially crafted SNMP request to the vulnerable application, possibly resulting in a high CPU and memory consumption.
There is no known workaround at this time.
All Net-SNMP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.4.1-r1"
