Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.82%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An integer overflow can occur in the SwizzleData code while calculating buffer sizes. The overflowed value is used for subsequent graphics computations when their inputs are not sanitized which results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Firefox ESR < 60.1, and Firefox < 61.
