CVE-2018-12393

Priority
Description
A potential vulnerability was found in 32-bit builds where an integer
overflow during the conversion of scripts to an internal UTF-16
representation could result in allocating a buffer too small for the
conversion. This leads to a possible out-of-bounds write. *Note: 64-bit
builds are not vulnerable to this issue.*. This vulnerability affects
Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.
