Brightmail Spamfilter 6.0 and earlier beta releases allows remote attackers to read mail from other users by modifying the id parameter in a viewMsgDetails.do request.

Multiple vulnerabilities in SYMDNS.SYS for Symantec Norton Internet Security and Professional 2002 through 2004, Norton Personal Firewall 2002 through 2004, Norton AntiSpam 2004, Client Firewall 5.01 and 5.1.1, and Client Security 1.0 through 2.0 allow remote attackers to cause a denial of service or execute arbitrary code via (1) a manipulated length byte in the first-level decoding routine for NetBIOS Name Service (NBNS) that modifies an index variable and leads to a stack-based buffer overflow, (2) a heap-based corruption problem in an NBNS response that is missing certain RR fields, and (3) a stack-based buffer overflow in the DNS component via a Resource Record (RR) with a long canonical name (CNAME) field composed of many smaller components.

The SYMDNS.SYS driver in Symantec Norton Internet Security and Professional 2002 through 2004, Norton Personal Firewall 2002 through 2004, Norton AntiSpam 2004, Client Firewall 5.01 and 5.1.1, and Client Security 1.0 through 2.0 allows remote attackers to cause a denial of service (CPU consumption from infinite loop) via a DNS response with a compressed name pointer that points to itself.

Stack-based buffer overflow in the SymSpamHelper ActiveX component (symspam.dll) in Norton AntiSpam 2004, as used in Norton Internet Security 2004, allows remote attackers to execute arbitrary code via a long parameter to the LaunchCustomRuleWizard method.

Cross-site scripting (XSS) vulnerability in Zaep AntiSpam 2.0 allows remote attackers to inject arbitrary web script or HTML via double encoded slashes (%252F) in the key parameter.
