Symantec Client Security 3.1.394

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.

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.

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.

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.

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.

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.

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 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.
