exiv2 -pSon a JP2 whose FileTypeBox sets its length below the 8-byte box header:box.length - boxHSizeunderflows, soBlobis sized to near SIZE_MAX andstd::vectorthrowsstd::length_errorrather than anExiv2::Error. The sibling sub-box and uuid cases already guardlength; this adds the same check before the FileTypeBox allocation.This is an automatic backport of pull request #9318 done by [Mergify](https://mergify.com).
