Using SVG filters that don't use the fixed point math implementation on a target iframe, a malicious page can extract pixel values from a targeted user. This can be used to extract history information and read text values across domains. This violates same-origin policy and leads to information disclosure. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8.

Security readout for executives and security teams

This is an older Mozilla browser and mail-client information disclosure flaw. A malicious page could abuse SVG filter behavior to infer pixel data from another domain, potentially exposing visited-page history or text rendered in a cross-domain iframe. Exposure is most likely where legacy Firefox, Firefox ESR, or Thunderbird builds remain in use, including older Linux distribution packages. Current supported Mozilla versions should not be assumed affected from the provided evidence. Treat this as a legacy-client cleanup issue unless affected versions are still present. Business urgency rises if outdated browsers or mail clients are used for sensitive internal applications or privileged workflows. Mitigation focus: Upgrade Firefox to version 52 or later.; Upgrade Firefox ESR to version 45.8 or later.; Upgrade Thunderbird to version 52 or later..
