Vulnerability Description
The snmp_trap_decode function in the SNMP NAT helper for Linux kernel before 2.6.16.18 allows remote attackers to cause a denial of service (crash) via unspecified remote attack vectors that cause failures in snmp_trap_decode that trigger (1) frees of random memory or (2) frees of previously-freed memory (double-free) by snmp_trap_decode as well as its calling function, as demonstrated via certain test cases of the PROTOS SNMP test suite.

Vulnerability Title
Linux Kernel SNMP NAT Helper snmp_trap_decode()函数 远程拒绝服务漏洞
Vulnerability Description
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 Linux Kernel在处理SNMP报文时存在拒绝服务漏洞，远程攻击者可能利用此漏洞导致内核崩溃。 当Kernel加载ip_nat_snmp_basic模块时会对来自UDP 161/162端口上的报文做NAT，snmp_trap_decode()函数实现上的问题会导致多次释放同一内存，最终导致内存破坏从而内核崩溃。
