Symantec : Security Vulnerabilities, CVEs, CVSS score >= 9

The default encryption method of PcAnywhere 9.x uses weak encryption, which allows remote attackers to sniff and decrypt PcAnywhere or NT domain accounts.

Norton AntiVirus 5.00.01C with the Novell Netware client does not properly restart the auto-protection service after the first user has logged off of the system.

Symantec LiveUpdate before 1.6 does not use cryptography to ensure the integrity of download files, which allows remote attackers to execute arbitrary code via DNS spoofing of the update.symantec.com site.

Symantec Java! JIT (Just-In-Time) Compiler for Netscape Communicator 4.0 through 4.8 allows remote attackers to execute arbitrary Java commands via an applet that uses a jump call, which is not correctly compiled by the JIT compiler.

Sygate personal firewall 5.0 could allow remote attackers to bypass firewall filters via spoofed (1) source IP address of 127.0.0.1 or (2) network address of 127.0.0.0.

Multiple vulnerabilities in SYMDNS.SYS for Symantec Norton Internet Security and Professional 2002 through 2004, Norton Personal Firewall 2002 through 2004, Norton AntiSpam 2004, Client Firewall 5.01 and 5.1.1, and Client Security 1.0 through 2.0 allow remote attackers to cause a denial of service or execute arbitrary code via (1) a manipulated length byte in the first-level decoding routine for NetBIOS Name Service (NBNS) that modifies an index variable and leads to a stack-based buffer overflow, (2) a heap-based corruption problem in an NBNS response that is missing certain RR fields, and (3) a stack-based buffer overflow in the DNS component via a Resource Record (RR) with a long canonical name (CNAME) field composed of many smaller components.

A certain ActiveX control in Symantec Norton AntiVirus 2004 allows remote attackers to cause a denial of service (resource consumption) and possibly execute arbitrary programs.

The Sun Java Plugin capability in Java 2 Runtime Environment (JRE) 1.4.2_01, 1.4.2_04, and possibly earlier versions, does not properly restrict access between Javascript and Java applets during data transfer, which allows remote attackers to load unsafe classes and execute arbitrary code by using the reflection API to access private Java packages.

Multiple unknown vulnerabilities in the ActiveX and HTML file browsers in Symantec Clientless VPN Gateway 4400 Series 5.0 have unknown attack vectors and unknown impact.

Symantec AntiVirus 9 Corporate Edition allows local users to gain privileges via the "Scan for viruses" option, which launches a help window with raised privileges, a re-introduction of a vulnerability that was originally identified and addressed by CVE-2002-1540.

Integer signedness error in the administrative interface for Symantec AntiVirus Scan Engine 4.0 and 4.3 allows remote attackers to execute arbitrary code via crafted HTTP headers with negative values, which lead to a heap-based buffer overflow.

Symantec Scan Engine 5.0.0.24, and possibly other versions before 5.1.0.7, uses a client-side check to verify a password, which allows remote attackers to gain administrator privileges via a modified client that sends certain XML requests.

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 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 does not properly check for chained commands, which allows remote attackers to execute arbitrary commands by appending malicious commands to valid commands.

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 CONNECT_OPTIONS request, a different issue than CVE-2006-6222.

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.

Multiple buffer overflows in the SupportSoft (1) SmartIssue (tgctlsi.dll) and (2) ScriptRunner (tgctlsr.dll) ActiveX controls, as used by Symantec Automated Support Assistant and Norton AntiVirus, Internet Security, and System Works 2006, allows remote attackers to execute arbitrary code via a crafted HTML message.

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

Multiple buffer overflows in the CentennialIPTransferServer service (XFERWAN.EXE), as used by (1) Centennial Discovery 2006 Feature Pack 1, (2) Numara Asset Manager 8.0, and (3) Symantec Discovery 6.5, allow remote attackers to execute arbitrary code via long strings in a crafted TCP packet.

Buffer overflow in Symantec Mail Security for SMTP 5.0 before Patch 175 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted headers in an e-mail message. NOTE: some information was obtained from third party sources.

Buffer overflow in the ISAlertDataCOM ActiveX control in ISLALERT.DLL for Norton Personal Firewall 2004 and Internet Security 2004 allows remote attackers to execute arbitrary code via long arguments to the (1) Get and (2) Set functions.

The Scheduler Service (VxSchedService.exe) in Symantec Storage Foundation for Windows 5.0 allows remote attackers to bypass authentication and execute arbitrary code via certain requests to the service socket that create (1) PreScript or (2) PostScript registry values under Veritas\VxSvc\CurrentVersion\Schedules specifying future command execution.

The agent remote upgrade interface in Symantec Enterprise Security Manager (ESM) before 20070405 does not verify the authenticity of upgrades, which allows remote attackers to execute arbitrary code via software that implements the agent upgrade protocol.

Stack-based buffer overflow in XferWan.exe as used in multiple products including (1) Symantec Discovery 6.5, (2) Numara Asset Manager 8.0, and (3) Centennial UK Ltd Discovery 2006 Feature Pack, allows remote attackers to execute arbitrary code via a long request. NOTE: this might be a reservation duplicate of CVE-2007-1173.

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.
