CVE-2011-2813
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 · uneditedWebKit, as used in Apple iTunes before 10.5, allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors related to iTunes Store browsing, a different vulnerability than other CVEs listed in APPLE-SA-2011-10-11-1.
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 · moderate confidenceMemory corruption vulnerability in WebKit rendering engine used by Apple iTunes before version 10.5 allows man-in-the-middle attackers to achieve arbitrary code execution or cause denial of service when users browse the iTunes Store.

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 iTunes installation and versionOpen iTunes, go to Help > About iTunes to display the version number. Alternatively, locate iTunes.exe file properties or check the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\Apple Computer, Inc.\iTunes for the Version value.Affected if Installed version matches <= 10.4.1 or equals any of 4.0.0, 4.0.1, 4.1.0, 4.2.0, 4.5.0, 4.6.0, 4.7.0, 4.7.1, 4.7.2, 4.8.0, or 4.9.0
-
Confirm iTunes Store browsing capabilityLaunch iTunes and verify whether the iTunes Store feature is accessible via the Store menu or the iTunes Store icon in the source pane.Affected if The iTunes Store is reachable or sign-in is possible, as this is the attack vector requiring network communication where a man-in-the-middle attack could occur
-
Check WebKit component presenceInspect the iTunes application directory for WebKit-related DLL files such as WebKit.dll or WebKit2.dll, which contain the vulnerable rendering engine.Affected if WebKit DLL files exist within the iTunes installation directory, indicating the vulnerable component is present
User is affected if iTunes version is 10.4.1 or earlier, or matches any of the specific older versions listed, and the iTunes Store feature is accessible for browsing.

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 dataUpdate Apple iTunes to version 10.5 or later to obtain the patched WebKit component; alternatively, avoid browsing the iTunes Store on untrusted networks until the update is applied.
