CVE-2010-5157
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 · uneditedRace condition in Comodo Internet Security before 4.1.149672.916 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack.
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 confidenceA race condition in Comodo Internet Security before version 4.1.149672.916 on Windows XP allows a local attacker to bypass kernel-mode hook handlers by manipulating user-space memory during hook-handler execution. This enables dangerous code execution that would normally be blocked by behavioral detection but not by signature-based malware detection, known as an argument-switch or KHOBE attack.

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.
-
Verify Comodo Internet Security is installedCheck for Comodo Internet Security in Add/Remove Programs (appwiz.cpl), or look in C:\Program Files\Comodo\ for the installation directory, or query the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ for Comodo Internet SecurityAffected if Comodo Internet Security is not found on the system, then this CVE does not apply
-
Identify the installed Comodo Internet Security versionOpen Add/Remove Programs, locate Comodo Internet Security, and note the version number displayed; alternatively, right-click the COMODO icon in the system tray and select About to view the versionAffected if The displayed version is 4.0.141842.828 or lower, or any version below 4.1.149672.916
-
Confirm the operating system is Windows XPOpen command prompt and run 'winver' or check System Properties; the vulnerability specifically affects Windows XP as noted in the CVE descriptionAffected if The system is running Windows XP and Comodo Internet Security version is below 4.1.149672.916
-
Compare installed version against affected rangeIf the exact version cannot be determined through the GUI, check the program's version info: right-click the COMODO executable (usually in C:\Program Files\Comodo\Comodo Internet Security\cmd.exe or similar) and select Properties > Details to view the File VersionAffected if File version shows 4.0.141842.828 or lower, or the version string begins with 4.0 rather than 4.1
A system is affected if Comodo Internet Security is installed with version 4.0.141842.828 or lower on Windows XP, specifically when the behavioral detection hooks are active (they are enabled by default in this product).

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.
From vendor dataUpgrade Comodo Internet Security to version 4.1.149672.916 or later; for systems running Windows XP, consider migrating to a supported operating system as Windows XP is end-of-life.
