CVE-2023-47040
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 · uneditedAdobe Media Encoder version 24.0.2 (and earlier) and 23.6 (and earlier) are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code 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 read vulnerability when parsing a crafted media file. The vulnerability occurs in the file parsing logic where insufficient bounds checking allows reading past the end of an allocated memory buffer. This memory corruption could be leveraged to achieve arbitrary code execution in the context of the current user. Exploitation requires user interaction: the victim must open a malicious file.

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 Adobe Media Encoder is installedCheck for Adobe Media Encoder in the list of installed applications. On Windows, check Program Files or Program Files (x86) for an Adobe Media Encoder folder, or use the system registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall to find the product.Affected if Adobe Media Encoder is found installed on the system
-
Determine the installed version numberOpen Adobe Media Encoder and go to Help > About Adobe Media Encoder, or check the application executable file properties for the version info. The version is typically displayed as a three-part number like 23.6.0 or 24.0.2.Affected if The installed version is 23.6.0 or lower, OR between 24.0.0 and 24.0.2 inclusive
-
Confirm the application handles media filesVerify that the Adobe Media Encoder application has been used to process or is capable of processing media files. The vulnerability is triggered during file parsing when a user opens a crafted media file.Affected if The application can open and parse media files, which is the default functionality of Media Encoder
-
Check for recent file processing activityReview the application log files or recently accessed media files in the user's profile or application data folders. Look for any .mp4, .mov, .avi, or other media file types that may have been processed.Affected if There is evidence of recent media file processing using Adobe Media Encoder, indicating the vulnerable code path could have been executed
A user is affected if Adobe Media Encoder is installed with a version between 24.0.0 and 24.0.2 or at 23.6.0 or lower, and the application is used to process media 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 Adobe Media Encoder to the latest version (newer than 24.0.2 or 23.6) to obtain the vendor patch. Avoid opening media files from untrusted sources until the update is applied.
