MEDIUM 6.5EPSS 3.16%

Does this matter?

Lower severity and a low EPSS score (3.16%). Track it; it rarely justifies an emergency change on its own.

Description

An invalid grid size during QCMS (color profile) transformations can result in the out-of-bounds read interpreted as a float value. This could leak private data into the output. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
