CVE-2015-0071
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 · uneditedMicrosoft Internet Explorer 9 through 11 allows remote attackers to bypass the ASLR protection mechanism via a crafted web site, aka "Internet Explorer ASLR Bypass 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 confidenceMicrosoft Internet Explorer versions 9 through 11 contains a vulnerability that allows remote attackers to bypass the ASLR (Address Space Layout Randomization) security protection mechanism by tricking users into visiting a crafted website. This bypass makes it easier for attackers to exploit other memory corruption vulnerabilities, though it does not directly result in code execution.

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.
-
Confirm Internet Explorer is installedCheck for IE in the system: open Programs and Features, look for 'Internet Explorer' entry, or check registry key HKLM\SOFTWARE\Microsoft\Internet Explorer for a Version valueAffected if Internet Explorer is present on the system
-
Identify the installed IE versionOpen Internet Explorer, click the gear icon (Settings), then 'About Internet Explorer' to view the version number; alternatively, check the Version value in HKLM\SOFTWARE\Microsoft\Internet Explorer in the registryAffected if The version shown is 9.0, 10.0, or 11.0 (any build within these major versions)
-
Determine if IE is actively usedCheck if IE is set as the default browser (Settings > Default apps > Web browser), or review browser usage logs or enterprise software inventory to see if users launch IEAffected if IE is configured as the default browser or users regularly launch and browse with Internet Explorer
Your environment is affected if Internet Explorer versions 9, 10, or 11 is installed AND users browse the web with IE, as the ASLR bypass can be triggered when visiting crafted websites.

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 dataApply the relevant Microsoft security update for Internet Explorer to address this vulnerability, or consider using alternative browsers until the patch can be deployed. Ensure Windows systems are configured to receive automatic security updates.
