PDF.js vulnerable to arbitrary JavaScript execution upon opening a malicious PDF
Impact
If pdf.js is used to load a malicious PDF, and PDF.js is configured with isEvalSupported set to true (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain.
Patches
The patch removes the use of eval:

Workarounds
Set the option isEvalSupported to false.
