CVE-2012-0660
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 · uneditedBuffer underflow in QuickTime in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MPEG file.
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 buffer underflow vulnerability exists in QuickTime in Apple Mac OS X versions prior to 10.7.4. The vulnerability is triggered when QuickTime parses a specially crafted MPEG file, allowing an attacker to write data before the start of a buffer. This can lead to arbitrary code execution with the privileges of the user running QuickTime, or cause the application to crash.

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.
-
Check your Mac OS X versionOpen Terminal and run: sw_vers -productVersionAffected if The version shown is 10.7.3 or lower, OR exactly matches 10.0, 10.0.0, 10.0.1, 10.0.2, 10.0.3, 10.0.4, 10.1, 10.1.0, 10.1.1, 10.1.2, or 10.1.3
-
Confirm QuickTime is installedCheck for /System/Library/Frameworks/QuickTime.framework or run: ls /Applications | grep -i quicktimeAffected if QuickTime.framework exists on the system (it is pre-installed on Mac OS X)
-
Verify the specific vulnerable version rangeCompare your OS version output from step 1 against the affected list: versions 10.0 through 10.7.3 inclusive, and versions 10.0.x and 10.1.x seriesAffected if Your installed version appears in the affected version list provided in the CVE
You are affected if your Mac OS X version is 10.7.3 or lower, or matches any of the specific 10.0.x or 10.1.x versions listed, and you use QuickTime to open MPEG files.

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 Mac OS X to version 10.7.4 or later, which includes the patched QuickTime component. Alternatively, avoid opening untrusted MPEG files from unknown sources in QuickTime until the update is applied.
