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.

Buffer overflow in the Trend Micro Scan Engine 8.000 and 8.300 before virus pattern file 4.245.00, as used in other products such as Cyber Clean Center (CCC) Cleaner, allows remote attackers to execute arbitrary code via a malformed UPX compressed executable.

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.

The Downloadable RADIUS ACLs feature in Cisco PIX and VPN 3000 concentrators, when creating an ACL on the Cisco Secure Access Control Server (CS ACS), generates a random internal name for an ACL that is also used as a hidden user name and password, which allows remote attackers to gain privileges by sniffing the username from the cleartext portion of a RADIUS session, then using the password to log in to another device that uses CS ACS.
