CVE-2009-1430
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple 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.

dbcve analysis · high confidenceStack-based buffer overflow in IAO.EXE (Intel Alert Originator) in Symantec Alert Management System 2 allows remote attackers to execute arbitrary code via crafted packets or malicious data from the MsgSys.exe process. The vulnerability affects multiple enterprise antivirus and security products from Symantec.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Symantec product and versionCheck Windows registry at HKLM\SOFTWARE\Symantec\InstalledApps for product names, and version in HKLM\SOFTWARE\Symantec\Version (or similar path under the specific product key)Affected if Product is one of: Symantec Antivirus (versions <=9.0, <=10.1, <=10.2, 10.0.x, 10.0.1.x, 10.0.2.x, 10.0.3, 10.0.4), Symantec Antivirus Central Quarantine Server (any version), Symantec Client Security (versions <=3.1, 2.0, 3.0.x, 3.0.0.359, 3.0.1.x, 3.0.2.x), Symantec Endpoint Protection (<=11.0), o
-
Verify Alert Management System component is presentCheck for existence of IAO.EXE in the Symantec product installation directory (typically in C:\Program Files\Symantec\ or subdirectories such as\Symantec Endpoint Protection\ or\Symantec\Alert Management System\)Affected if IAO.EXE file exists in the installation directory, indicating the vulnerable component is present
-
Check if Alert Management System service is runningOpen Services control panel or run 'sc query' command and look for a service named 'Alert Management System' or 'Symantec Alert Management System' and check its statusAffected if The Alert Management System service is installed and running
-
Detect IAO.EXE and MsgSys.exe processesOpen Task Manager or run 'tasklist' command and look for processes named IAO.EXE and MsgSys.exeAffected if Both IAO.EXE and MsgSys.exe processes are actively running, confirming the vulnerable code path is in use
You are affected if you have any of the listed Symantec products in the vulnerable version ranges AND the IAO.EXE component (Alert Management System) is present and running.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply vendor-supplied patches (MR7/MR8/MR3 depending on product version) to upgrade to patched versions of the affected Symantec products, or disable the Alert Management System service if not required.
Product-specific MR (Maintenance Release) versions: 9.0 MR7, 10.1 MR8, 10.2 MR2, 2.0 MR7, 3.1 MR8, or 11.0 MR3 (whichever applies to your product line)
- Identify the specific Symantec product and current version from the affected list (Antivirus, Client Security, Endpoint Protection, or System Center)
- For Symantec AntiVirus 9.x: upgrade to version 9.0 MR7 or later
- For Symantec AntiVirus 10.0/10.1: upgrade to version 10.1 MR8 or later
- For Symantec AntiVirus 10.2: upgrade to version 10.2 MR2 or later
- For Symantec Client Security 2.x: upgrade to version 2.0 MR7 or later
- For Symantec Client Security 3.x: upgrade to version 3.1 MR8 or later
- For Symantec Endpoint Protection: upgrade to version 11.0 MR3 or later
- For Symantec AntiVirus Central Quarantine Server: contact Symantec for specific patch or upgrade path
