CVE-2017-2975
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 Digital Editions versions 4.5.3 and earlier have an exploitable buffer over-read 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 4.5.3 and earlier contain a buffer over-read vulnerability that can be triggered during e-book parsing operations, allowing an attacker to read sensitive memory contents beyond allocated buffers and disclose information to an unauthenticated remote attacker.

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.
-
Identify installed Adobe Digital Editions versionOn Windows, open Control Panel > Programs and Features and locate Adobe Digital Editions to view the version number. On macOS, right-click the Adobe Digital Editions application in /Applications, select Get Info, and check the Version field. Alternatively, right-click the executable (DigitalEditions.exe on Windows or Adobe Digital Editions.app on macOS), select Properties, and view the Details tab for version information.Affected if The displayed version is 4.5.3 or any version number lower than 4.5.3 (for example, 4.5.2, 4.5.1, 4.5.0, 4.0.x, etc.)
-
Confirm e-book parsing capability is presentVerify that Adobe Digital Editions is installed with its core e-book parsing libraries intact. Check that the application directory contains the default resources folder (such as resources/ or lib/ folders where parsing modules reside) and that no modifications have been made to remove e-book handling functionality.Affected if The application retains full e-book parsing capability, meaning it can open and process EPUB, PDF, or other e-book file formats typically supported by Adobe Digital Editions
-
Verify the application is in active use or accessibleCheck whether Adobe Digital Editions is currently installed on a system that processes e-book files. Review any scheduled tasks, file associations, or automation that may cause the application to automatically open or process e-book files without user interaction.Affected if The software is installed and operational on a system, or file associations are configured such that e-book files can trigger the application to parse them automatically
A system is affected if Adobe Digital Editions version 4.5.3 or earlier is installed and the application retains its e-book parsing functionality, allowing untrusted e-book files to trigger the buffer over-read.

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 version 4.5.4 or later. If immediate patching is not feasible, restrict handling of untrusted e-book files and network access to systems running the vulnerable software.
