Comment 23 for bug 2039804

This bug was fixed in the package qpdf - 11.5.0-1ubuntu1

---------------
qpdf (11.5.0-1ubuntu1) mantic; urgency=medium

  * Fix data loss bug introduced in 11.0.0 and fixed in 11.6.3. The bug
    causes the qpdf tokenizer to discard the character after a one-digit
    or two-digit quoted octal string. Most writers don't create these, and
    they are rare outside of content streams. By default, qpdf doesn't
    parse content streams. The most common place for this to occur would
    be in a document's /ID string, but in the worst case, this bug could
    cause silent damage to some strings in a PDF file's metadata, such as
    bookmark names or form field values. (LP: #2039804)
