    CVE-2015-5621

    Published: 19 Aug 2015Last Modified: 10 Apr 2026

    Summary:

    Details: The snmp_pdu_parse function in snmp_api.c in net-snmp 5.7.2 and earlier does not remove the varBind variable in a netsnmp_variable_list item when parsing of the SNMP PDU fails, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted packet.
