This signature detects SNMP packets containing incorrect trap information for the decode() function. An attacker can send crafted packets to a Linux NAT device and can cause the target system to become unresponsive. Linux kernels 2.6.16 and earlier may be vulnerable.
The Linux SNMP NAT helper is susceptible to a remote denial-of-service vulnerability. This issue allows remote attackers to potentially corrupt memory and ultimately trigger a denial of service for legitimate users. Kernel versions prior to 2.6.16.18 are vulnerable to this issue.
