Mozilla Firefox 7.0 and Thunderbird 7.0, when the Direct2D (aka D2D) API is used on Windows in conjunction with the Azure graphics back-end, allow remote attackers to bypass the Same Origin Policy, and obtain sensitive image data from a different domain, by inserting this data into a canvas. NOTE: this issue exists because of a CVE-2011-2986 regression.

Security readout for executives and security teams

This is an old Mozilla browser/email-client issue where certain Windows graphics settings could let a malicious web page break browser isolation and read image data from another domain through canvas. The main business concern is exposure of sensitive visual data in legacy Firefox or Thunderbird 7.0 deployments. Likely exposure is limited to legacy Windows systems still running Firefox 7.0 or Thunderbird 7.0 with the affected graphics path. Modern, supported Mozilla versions are not identified as affected in the provided sources. Treat this as a legacy-software cleanup issue unless vulnerable versions are still present. If found, prioritize replacement because the flaw weakens browser isolation and could expose sensitive visual data across origins. Mitigation focus: Inventory and retire Firefox 7.0 and Thunderbird 7.0 installations.; Apply vendor updates referenced by Mozilla or operating-system advisories.; Check Mozilla guidance before assuming a specific fixed version..
