The PDF viewer in Google Chrome before 46.0.2490.86 does not properly restrict scripting messages and API exposure, which allows remote attackers to bypass the Same Origin Policy via an unintended embedder or unintended plugin loading, related to pdf.js and out_of_process_instance.cc.

Security readout for executives and security teams

CVE-2015-1302 is an old Google Chrome PDF viewer flaw. In vulnerable Chrome versions, a malicious remote page could bypass browser same-origin protections through improper PDF viewer scripting and API exposure. The practical business concern is legacy or unpatched browser installations, not modern supported Chrome. Exposure is most likely on systems still running Google Chrome before 46.0.2490.86 or downstream Linux browser packages covered by the cited 2015 advisories. Modern managed browsers should not be exposed if they receive normal vendor updates. Treat this as a legacy hygiene issue unless old browsers are still present. It should be prioritized through endpoint patch compliance and unsupported software retirement, not as an emergency response without evidence of active exploitation. Mitigation focus: Upgrade Chrome or Chromium-derived packages to vendor-supported fixed versions.; Ensure Google Chrome is at least 46.0.2490.86 where legacy baselines matter.; Apply relevant Red Hat, Debian, openSUSE, or Gentoo security updates..
