MuPDF
was a full featured version of the super lightweight mupdf viewer
, which supported annotations and selecting text, mobile view.
After mupdf library was reported with 4 CVEs (3 of them regarding xps files and an integer overflow), upstream perhaps didn’t continue full version mupdf
. They rather continued / created a stripped down version called mupdf viewer
. It doesn’t have mobile view / text selection AFAIK.
Since the vulnerabilities appear to be due to underlying library, is it possible to build original mupdf
with new libs? bringing a PDF viewer with text selection and mobile view to fdroid.
In such a case, full network access
permission shall be removed, because simply it causes people stay away from the app.
Currently, pen&pdf
by C Gogolin is only opensource pdf viewer that allows to select text and highlight / annotate. It is there on submission queue. Hope it too would be built without internet permissions if built – since those permissions are required for Google cloud print apis that we don’t use.
