Out-of-bounds array write in Xpdf 4.05 and earlier, due to missing object
type check in AcroForm field reference.

Notes

Author Note
mdeslaur In trusty to bionic, xpdf is built with poppler as the backend library, so most xpdf issues don’t apply to it. In jammy and later, the xpdf package is actually xpopple, a fork that also builds against poppler.
