eEye Security Advisory – eEye Digital Security has discovered a critical vulnerability in the Symantec firewall product line that would allow a remote, anonymous attacker to execute arbitrary code on a system running an affected version of the product. By sending a single specially-crafted NetBIOS Name Service (UDP port 137) packet to a vulnerable host, an attacker could cause an arbitrary memory location to be overwritten with data he or she controls, leading to the execution of attacker-supplied code with kernel privileges and the absolute compromise of the target. Systems Affected: Symantec Norton Internet Security 2002/2003/2004, Symantec Norton Internet Security Professional 2002/2003/2004, Symantec Norton Personal Firewall 2002/2003/2004, Symantec Client Firewall 5.01/5.1.1, Symantec Client Security 1.0/1.1/2.0(SCF 7.1), and Symantec Norton AntiSpam 2004.
