Mozilla Gecko before 5.0, as used in Firefox before 5.0 and Thunderbird before 5.0, does not block use of a cross-domain image as a WebGL texture, which allows remote attackers to obtain approximate copies of arbitrary images via a timing attack involving a crafted WebGL fragment shader.

Security readout for executives and security teams

This is an old Mozilla browser-engine privacy flaw. A malicious web page could abuse WebGL handling of cross-domain images to infer approximate image contents that should have remained protected. The sources identify Firefox, Thunderbird, and Mozilla Gecko before version 5.0. Exposure is most plausible on legacy systems still running Firefox, Thunderbird, or Gecko-based software before 5.0. Modern, vendor-supported Mozilla releases should not be exposed to this specific issue if updated. Low immediate priority for normally maintained environments, but verify there are no legacy browser dependencies. Prioritize remediation if regulated data or sensitive internal images are accessed from outdated clients. Mitigation focus: Upgrade affected Firefox, Thunderbird, or Gecko deployments to version 5.0 or later.; Prefer current vendor-supported Mozilla releases, not merely historically fixed versions.; If upgrade is delayed, follow Mozilla guidance for WebGL and cross-domain texture handling..
