CVE-2024-41858
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 · uneditedInCopy versions 18.5.2, 19.4 and earlier are affected by an Integer Overflow or Wraparound 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 confidenceThis is an integer overflow or wraparound vulnerability in Adobe InCopy that allows arbitrary code execution when a user opens a specially crafted malicious file. The integer overflow can be exploited to overwrite memory and execute arbitrary code in the context of the current user session.

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.
-
Locate Adobe InCopy installationCheck common installation paths such as C:\Program Files\Adobe\Adobe InCopy 2024\ or C:\Program Files (x86)\Adobe\Adobe InCopy 2024\, or use the Windows Programs and Features control panel to list installed software.Affected if Adobe InCopy is installed on the system
-
Identify installed InCopy version numberIn Windows, right-click the InCopy application in Programs and Features and select Properties, then view the Version field. Alternatively, open InCopy, go to Help > About InCopy to see the full version number.Affected if The version displayed is 18.5.2 or lower, OR any version from 19.0 through 19.3.x
-
Compare version against CVE rangeParse the version number identified in step 2. Affected versions are: all releases <= 18.5.2, and releases >= 19.0 but < 19.4. Versions 19.4 and later, or versions between 18.5.3 and 18.x.x before 19.0, are NOT affected.Affected if The installed version falls within <= 18.5.2 or >= 19.0 and < 19.4
-
Assess user exposure to malicious filesDetermine if users routinely open InCopy files from external sources, email attachments, or untrusted downloads. Check browser download folders and common document share locations for .icml or other InCopy file types.Affected if Users open InCopy files from untrusted or unknown sources, or the system lacks endpoint protection against malicious documents
The environment is affected if Adobe InCopy is installed with a version number matching <= 18.5.2 or >= 19.0 and < 19.4, AND users may open files from untrusted sources.
