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."

Buffer overflow in the cliproxy.objects.1 ActiveX control in the Symantec Client Proxy (CLIproxy.dll) in Symantec AntiVirus 10.0.x, 10.1.x before MR9, and 10.2.x before MR4; and Symantec Client Security 3.0.x and 3.1.x before MR9 allows remote attackers to execute arbitrary code via a long argument to the SetRemoteComputerName function.

The on-demand scanning in Symantec AntiVirus 10.0.x and 10.1.x before MR9, AntiVirus 10.2.x, and Client Security 3.0.x and 3.1.x before MR9, when Tamper protection is disabled, allows remote attackers to cause a denial of service (prevention of on-demand scanning) via "specific events" that prevent the user from having read access to unspecified resources.

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.

XFR.EXE in the Intel File Transfer service in the console in Symantec Alert Management System 2 (AMS2), as used in Symantec System Center (SSS); Symantec AntiVirus Server; Symantec AntiVirus Central Quarantine Server; Symantec AntiVirus (SAV) Corporate Edition 9 before 9.0 MR7, 10.0 and 10.1 before 10.1 MR8, and 10.2 before 10.2 MR2; Symantec Client Security (SCS) 2 before 2.0 MR7 and 3 before 3.1 MR8; and Symantec Endpoint Protection (SEP) before 11.0 MR3, allows remote attackers to execute arbitrary code by placing the code on a (1) share or (2) WebDAV server, and then sending the UNC share pathname to this service.

Multiple stack-based buffer overflows in IAO.EXE in the Intel Alert Originator Service in Symantec Alert Management System 2 (AMS2), as used in Symantec System Center (SSS); Symantec AntiVirus Server; Symantec AntiVirus Central Quarantine Server; Symantec AntiVirus (SAV) Corporate Edition 9 before 9.0 MR7, 10.0 and 10.1 before 10.1 MR8, and 10.2 before 10.2 MR2; Symantec Client Security (SCS) 2 before 2.0 MR7 and 3 before 3.1 MR8; and Symantec Endpoint Protection (SEP) before 11.0 MR3, allow remote attackers to execute arbitrary code via (1) a crafted packet or (2) data that ostensibly arrives from the MsgSys.exe process.

The Intel LANDesk Common Base Agent (CBA) in Symantec Alert Management System 2 (AMS2), as used in Symantec System Center (SSS); Symantec AntiVirus Server; Symantec AntiVirus Central Quarantine Server; Symantec AntiVirus (SAV) Corporate Edition 9 before 9.0 MR7, 10.0 and 10.1 before 10.1 MR8, and 10.2 before 10.2 MR2; Symantec Client Security (SCS) 2 before 2.0 MR7 and 3 before 3.1 MR8; and Symantec Endpoint Protection (SEP) before 11.0 MR3, allows remote attackers to execute arbitrary commands via a crafted packet whose contents are interpreted as a command to be launched in a new process by the CreateProcessA function.

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

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.

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.

Unspecified vulnerability in Symantec Reporting Server 1.0.197.0, and other versions before 1.0.224.0, as used in Symantec Client Security 3.1 and later, and Symantec AntiVirus Corporate Edition (SAV CE) 10.1 and later, allows attackers to "disable the authentication system" and bypass authentication via unknown vectors.

Symantec Reporting Server 1.0.197.0, and other versions before 1.0.224.0, as used in Symantec Client Security 3.1 and later, and Symantec AntiVirus Corporate Edition (SAV CE) 10.1 and later, does not initialize a critical variable, which allows attackers to create arbitrary executable files via unknown manipulations of a file that is created during data export.

Symantec Reporting Server 1.0.197.0, and other versions before 1.0.224.0, as used in Symantec Client Security 3.1 and later, and Symantec AntiVirus Corporate Edition (SAV CE) 10.1 and later, displays the password hash for a user after a failed login attempt, which makes it easier for remote attackers to conduct brute force attacks.

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.

Stack-based buffer overflow in Symantec Antivirus 10.1 and Client Security 3.1 allows remote attackers to execute arbitrary code via unknown attack vectors.
