Alta
| Vetor | AV:N/AC:H/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 120
Firefox ESR versions prior to 115.5.0
Thunderbird versions prior to 115.5.0
Description
The issue is related to the WebGL2RenderingContext.blitFramebuffer() method in the WebGL2 interface of Firefox and Firefox ESR browsers, and the Thunderbird email client. It involves an out-of-bounds read operation in memory when processing canvas elements, potentially allowing a remote attacker to gain unauthorized access to protected information. This can occur on some systems, depending on the graphics settings and drivers, and may result in memory data being leaked into images created on the canvas element.
Recommendations
For Firefox versions prior to 120, update to version 120 or later.
For Firefox ESR versions prior to 115.5.0, update to version 115.5.0 or later.
For Thunderbird versions prior to 115.5.0, update to version 115.5.0 or later.
