The description says successful exploitation could lead to information disclosure.

Defensive priority

High. Systems that still run Adobe Digital Editions 4.5.3 or earlier should be prioritized for upgrade or removal from exposure.

Recommended defensive actions

  • Upgrade Adobe Digital Editions to a version newer than 4.5.3 on all affected systems.
  • Inventory endpoints that still have Adobe Digital Editions installed and confirm the installed version.
  • Reduce exposure to untrusted or unnecessary content handling in affected installations until patched.
  • Use standard endpoint protection and software restriction controls to limit the impact of vulnerable desktop applications.
  • Monitor vendor guidance linked from the Adobe PSIRT advisory APSB17-05 for remediation details.
