CVE-2007-0944
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 · uneditedUnspecified vulnerability in the CTableCol::OnPropertyChange method in Microsoft Internet Explorer 5.01 SP4 on Windows 2000 SP4; 6 SP1 on Windows 2000 SP4; and 6 on Windows XP SP2, or Windows Server 2003 SP1 or SP2 allows remote attackers to execute arbitrary code by calling deleteCell on a named table row in a named table column, then accessing the column, which causes Internet Explorer to access previously deleted objects, aka the "Uninitialized Memory Corruption Vulnerability."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMemory corruption vulnerability in Internet Explorer's CTableCol::OnPropertyChange method allows remote code execution when deleteCell is called on a named table row in a named table column, followed by accessing the column, causing use-after-free of deleted objects. Affects IE 5.01/6 on Windows 2000 SP4, XP SP2, and Server 2003 SP1/SP2.

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 Internet Explorer versionOpen Internet Explorer, click Help > About Internet Explorer, or run 'reg query "HKLM\SOFTWARE\Microsoft\Internet Explorer" /v Version' in Command PromptAffected if Version reports 5.01 or 6.0 (exactly)
-
Confirm Windows operating system versionRun 'winver' or check System Properties, or run 'systeminfo' in Command PromptAffected if Windows 2000 SP4, Windows XP SP2, or Windows Server 2003 SP1/SP2
-
Verify the CTableCol component is presentCheck that iexplore.exe exists in the Program Files folder and that the browser renders HTML tablesAffected if Internet Explorer is functional and capable of rendering HTML table elements
-
Check for deleteCell usage in web contentReview web application logs or code for use of JavaScript deleteCell method on table rows in named tablesAffected if Web applications use named tables with deleteCell operations on table rows
If Internet Explorer 5.01 or 6.0 is installed on Windows 2000 SP4, XP SP2, or Server 2003 SP1/SP2, the system is affected by this vulnerability and cannot be patched.

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 · scopedAll affected systems (Windows 2000, XP SP2, Server 2003) are end-of-life with no vendor patches available; remediate by migrating to supported Windows versions and browsers, or isolate legacy systems on segmented networks.
Internet Explorer 7 or higher (or Microsoft Edge on supported Windows 10/11 systems)
- 1. Apply Microsoft security update MS07-027 (Cumulative Security Update for Internet Explorer) or later cumulative update that addresses this vulnerability.
- 2. Upgrade Internet Explorer to version 7 or higher (IE 7, 8, 9, 10, or 11) which are not affected by this vulnerability.
- 3. Alternatively, migrate to Microsoft Edge browser for modern Windows systems.
