Heap-based buffer overflow in the Decomposer component in multiple Symantec products allows remote attackers to execute arbitrary code via multiple crafted CAB archives.

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.

The SymTDI device driver (SYMTDI.SYS) in Symantec Norton Personal Firewall 2006 9.1.1.7 and earlier, Internet Security 2005 and 2006, AntiVirus Corporate Edition 3.0.x through 10.1.x, and other Norton products, allows local users to cause a denial of service (system crash) by sending crafted data to the driver's \Device file, which triggers invalid memory access, a different vulnerability than CVE-2006-4855.

Multiple directory traversal vulnerabilities in Symantec Brightmail AntiSpam (SBAS) before 6.0.4, when the Control Center is allowed to connect from any computer, allow remote attackers to read and overwrite certain files via directory traversal sequences in (1) DATABLOB-GET and (2) DATABLOB-SAVE requests.

Symantec Brightmail AntiSpam (SBAS) before 6.0.4, when the Control Center is allowed to connect from any computer, allows remote attackers to cause a denial of service (application freeze) "by sending invalid posts".

Symantec Brightmail AntiSpam 6.0 build 1 and 2 allows remote attackers to cause a denial of service (bmserver component termination) via malformed MIME messages.

Symantec Brightmail AntiSpam before 6.0.2 has a hard-coded database administrator password, which allows remote attackers to gain privileges.

Heap-based buffer overflow in the DEC2EXE module for Symantec AntiVirus Library allows remote attackers to execute arbitrary code via a UPX compressed file containing a negative virtual offset to a crafted PE header.

The character converters in the Spamhunter and Language ID modules for Symantec Brightmail AntiSpam 6.0.1 before patch 132 allow remote attackers to cause a denial of service (crash) via messages with the ISO-8859-10 character set, which is not recognized by the converters.
