Symantec Messaging Gateway version 9.5.3-3 suffers from backdoor account and privilege escalation vulnerabilities.
0037358302ea3ef9e579ea39b29f6aeedaab8ea3fd730436e1fe43363d09f8dcThe Linux kernel failed to properly initialize some entries the proto_ops struct for several protocols, leading to NULL being derefenced and used as a function pointer. By using mmap(2) to map page 0, an attacker can execute arbitrary code in the context of the kernel. Several public exploits exist for this vulnerability, including spender's wunderbar_emporium and rcvalle's ppc port, sock_sendpage.c. All Linux 2.4/2.6 versions since May 2001 are believed to be affected: 2.4.4 up to and including 2.4.37.4; 2.6.0 up to and including 2.6.30.4
