When calling JS::CheckRegExpSyntax a Syntax Error could have been set
which would end in calling convertToRuntimeErrorAndClear. A path in the
function could attempt to allocate memory when none is available which
would have caused a newly created Out of Memory exception to be mishandled
as a Syntax Error. This vulnerability affects Firefox < 117, Firefox ESR <
115.2, and Thunderbird < 115.2.
