Buffer overflow in an ActiveX control (SYMLTCOM.dll) in Symantec N360 1.0 and 2.0; Norton Internet Security, AntiVirus, SystemWorks, and Confidential 2006 through 2008; and Symantec Client Security 3.0.x before 3.1 MR9, and 3.1.x before MR9; allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors. NOTE: this is only a vulnerability if the attacker can "masquerade as an authorized site."

Unspecified vulnerability in Symantec Norton AntiVirus 2005 through 2008; Norton Internet Security 2005 through 2008; AntiVirus Corporate Edition 9.0 before MR7, 10.0, 10.1 before MR8, and 10.2 before MR3; and Client Security 2.0 before MR7, 3.0, and 3.1 before MR8; when Internet Email Scanning is installed and enabled, allows remote attackers to cause a denial of service (CPU consumption and persistent connection loss) via unknown attack vectors.

The Disk Mount scanner in Symantec AntiVirus for Macintosh 9.x and 10.x, Norton AntiVirus for Macintosh 10.0 and 10.1, and Norton Internet Security for Macintosh 3.x, uses a directory with weak permissions (group writable), which allows local admin users to gain root privileges by replacing unspecified files, which are executed when a user with physical access inserts a disk and the "Show Progress During Mount Scans" option is enabled.

The Decomposer component in multiple Symantec products allows remote attackers to cause a denial of service (infinite loop) via a certain value in the PACK_SIZE field of a RAR archive file header.

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.

The \Device\SymEvent driver in Symantec Norton Personal Firewall 2006 9.1.0.33, and other versions of Norton Personal Firewall, Internet Security, AntiVirus, SystemWorks, Symantec Client Security SCS 1.x, 2.x, 3.0, and 3.1, Symantec AntiVirus Corporate Edition SAVCE 8.x, 9.x, 10.0, and 10.1, Symantec pcAnywhere 11.5 only, and Symantec Host, allows local users to cause a denial of service (system crash) via invalid data, as demonstrated by calling DeviceIoControl to send the data.

Untrusted search path vulnerability in unspecified components in Symantec LiveUpdate for Macintosh 3.0.0 through 3.5.0 do not set the execution path, which allows local users to gain privileges via a Trojan horse program.
