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 · unedited
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.2.1.53537. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Doc objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-16420.

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 confidence

This is a use-after-free or null pointer dereference vulnerability in Foxit PDF Reader 11.2.1.53537 where the Doc object handling routine fails to validate object existence before performing operations on it. An attacker can exploit this by crafting a malicious PDF file that, when opened, allows arbitrary code execution in the context of the current process.

MitigationApply the vendor patch from Foxit; until then, avoid opening untrusted PDF files and disable JavaScript execution in the PDF reader as a defense-in-depth measure.
