AVG Anti-Virus plus Firewall 7.5.431 relies on the Process Environment Block (PEB) to identify a process, which allows local users to bypass the product's controls on a process by spoofing the (1) ImagePathName, (2) CommandLine, and (3) WindowTitle fields in the PEB.

AntiHook 3.0.0.23 - Desktop relies on the Process Environment Block (PEB) to identify a process, which allows local users to bypass the product's controls on a process by spoofing the (1) ImagePathName, (2) CommandLine, and (3) WindowTitle fields in the PEB.

Stack-based buffer overflow in the NetBackup bpcd daemon (bpcd.exe) in Symantec Veritas NetBackup 5.0 before 5.0_MP7, 5.1 before 5.1_MP6, and 6.0 before 6.0_MP4 allows remote attackers to execute arbitrary code via a long request with a malformed length prefix.

The Symantec Messaging Gateway before 10.6.3-267 can encounter an issue of remote code execution, which describes a situation whereby an individual may obtain the ability to execute commands remotely on a target machine or in a target process. In this type of occurrence, after gaining access to the system, the attacker may attempt to elevate their privileges.

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.

SYMNDIS.SYS in Symantec Norton Internet Security 2003 and 2004, Norton Personal Firewall 2003 and 2004, Client Firewall 5.01 and 5.1.1, and Client Security 1.0 and 1.1 allow remote attackers to cause a denial of service (infinite loop) via a TCP packet with (1) SACK option or (2) Alternate Checksum Data option followed by a length of zero.

Format string vulnerability in the Real Time Virus Scan service in Symantec AntiVirus Corporate Edition 8.1 up to 10.0, and Client Security 1.x up to 3.0, allows local users to execute arbitrary code via an unspecified vector related to alert notification messages, a different vector than CVE-2006-3454, a "second format string vulnerability" as found by the vendor.

The proxy DNS service in Symantec Gateway Security (SGS) allows remote attackers to make arbitrary DNS queries to third-party DNS servers, while hiding the source IP address of the attacker. NOTE: another researcher has stated that the default configuration does not proxy DNS queries received on the external interface

Buffer overflow in Entrust LibKmp ISAKMP library, as used by Symantec Enterprise Firewall 7.0 through 8.0, Gateway Security 5300 1.0, Gateway Security 5400 2.0, and VelociRaptor 1.5, allows remote attackers to execute arbitrary code via a crafted ISAKMP payload.

The client for Symantec Norton AntiVirus Corporate Edition 7.5.x before 7.5.1 Build 62 and 7.6.x before 7.6.1 Build 35a runs winhlp32 with raised privileges, which allows local users to gain privileges by using certain features of winhlp32.

The manager server in Symantec Enterprise Security Manager (ESM) 6 and 6.5.x allows remote attackers to cause a denial of service (hang) via a malformed ESM agent request.

Symantec Norton Personal Firewall 2006 9.1.0.33, and possibly earlier, does not properly protect Norton registry keys, which allows local users to provide Trojan horse libraries to Norton by using RegSaveKey and RegRestoreKey to modify HKLM\SOFTWARE\Symantec\CCPD\SuiteOwners, as demonstrated using NISProd.dll. NOTE: in most cases, this attack would not cross privilege boundaries, because modifying the SuiteOwners key requires administrative privileges. However, this issue is a vulnerability because the product's functionality is intended to protect against privileged actions such as this.

The WrapNISUM ActiveX component (WrapUM.dll) in Norton Internet Security 2004 is marked safe for scripting, which allows remote attackers to execute arbitrary programs via the LaunchURL method.

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".

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.

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.

Secure Webserver 1.1 in Raptor 6.5 and Symantec Enterprise Firewall 6.5.2 allows remote attackers to identify IP addresses of hosts on the internal network via a CONNECT request, which generates different error messages if the host is present.

Configuration error in Axent Raptor Firewall 6.5 allows remote attackers to use the firewall as a proxy to access internal web resources when the http.noproxy Rule is not set.

Symantec pcAnywhere 12.5 uses weak integrity protection for .cif (aka caller or CallerID) files, which allows local users to generate a custom .cif file and modify the superuser flag.

Symantec pcAnywhere 12.5 obfuscates the passwords in a GUI textbox with asterisks but does not encrypt them in the associated .cif (aka caller or CallerID) file, which allows local users to obtain the passwords from the window using tools such as Nirsoft Asterwin.
