CVE-2024-39377
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 · uneditedMedia Encoder versions 24.5, 23.6.8 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious 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 confidenceAdobe Media Encoder contains an out-of-bounds write vulnerability that allows arbitrary code execution in the context of the current user. Exploitation requires victim interaction to open a malicious file, making this a local code execution issue dependent on social engineering.

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 Adobe Media Encoder is installedLocate the Adobe Media Encoder application in the system. Common installation paths include C:\Program Files\Adobe\Adobe Media Encoder or C:\Program Files (x86)\Adobe\Adobe Media Encoder on Windows, or /Applications/Adobe Media Encoder on macOS.Affected if Adobe Media Encoder is present on the system.
-
Identify the installed versionOpen Adobe Media Encoder and navigate to Help > About Adobe Media Encoder, or right-click the application file and select Properties to view version information. Alternatively, check the version in the Windows Registry under HKLM\SOFTWARE\Adobe\MediaEncoder or via the application's executable file properties.Affected if Unable to determine the version indicates potential incomplete installation or non-standard deployment.
-
Compare against affected version rangesReview the identified version number against the vulnerable ranges: any version below 23.6.9, or any version from 24.0 up to but not including 24.6.Affected if Installed version falls within < 23.6.9 or >= 24.0 and < 24.6.
-
Assess exploitation exposureDetermine whether the application processes media files from external or untrusted sources, as exploitation requires a user to open a maliciously crafted file.Affected if Users routinely open media files from unknown or untrusted sources, increasing the attack surface for this vulnerability.
A user is affected if Adobe Media Encoder is installed with a version less than 23.6.9 or between 24.0 and 24.5.x inclusive, and the application is used to open files from potentially untrusted sources.
