Symantec » Norton Antispam : Security Vulnerabilities, CVEs, CVSS score >= 4

Symantec symtdi.sys before 7.0.0, as distributed in Symantec AntiVirus Corporate Edition 9 through 10.1 and Client Security 2.0 through 3.1, Norton AntiSpam 2005, and Norton AntiVirus, Internet Security, Personal Firewall, and System Works 2005 and 2006; allows local users to gain privileges via a crafted Interrupt Request Packet (Irp) in an IOCTL 0x83022323 request to \\symTDI\, which results in memory overwrite.

SPBBCDrv.sys in Symantec Norton Personal Firewall 2006 9.1.0.33 and 9.1.1.7 does not validate certain arguments before being passed to hooked SSDT function handlers, which allows local users to cause a denial of service (crash) or possibly execute arbitrary code via crafted arguments to the (1) NtCreateMutant and (2) NtOpenEvent functions. NOTE: it was later reported that Norton Internet Security 2008 15.0.0.60, and possibly other versions back to 2006, are also affected.

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.

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.
