NVD · uneditedAdobe Digital Editions versions 4.5.7 and below have an exploitable Stack Overflow vulnerability. Successful exploitation could lead to information disclosure.
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 confidenceAdobe Digital Editions versions 4.5.7 and below contain a stack-based buffer overflow vulnerability. Successful exploitation allows an attacker to overflow a stack buffer, potentially leading to information disclosure through memory corruption.

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 if Adobe Digital Editions is installedOn Windows, check for the presence of Adobe Digital Editions in the Programs and Features control panel, or search for the executable (typically named ADE.exe) in Program Files or Program Files (x86) folders.Affected if Adobe Digital Editions is found on the system
-
Locate the installed executableFind the main Adobe Digital Editions executable file. Common paths include C:\Program Files\Adobe\Adobe Digital Editions or C:\Program Files (x86)\Adobe\Adobe Digital Editions. The executable is typically named ADE.exe or digitaleditions.exe.Affected if The executable exists at an Adobe Digital Editions installation path
-
Determine the installed versionRight-click the executable, select Properties, and view the Details tab to see the File Version. Alternatively, open Adobe Digital Editions and navigate to Help > About Adobe Digital Editions to display the version number.Affected if The displayed version is 4.5.7 or any version lower than 4.5.7
-
Compare version against affected rangeCompare your identified version number to the affected range: versions 4.5.7 and below. Note that version 4.5.7 itself is also affected.Affected if The installed version is 4.5.7 or below (for example: 4.5.6, 4.5.5, 4.5.4, etc.)
A system is affected if Adobe Digital Editions version 4.5.7 or any earlier version (such as 4.5.6, 4.5.5, etc.) is installed and the application is used to open untrusted EPUB/PDF 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 dataUpgrade Adobe Digital Editions to a version newer than 4.5.7. If a newer version is not available from Adobe, consider using alternative e-book reader software or implementing network-level controls to limit exposure to untrusted EPUB/PDF files.
