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.
