@@ -1,3 +1,16 @@ +2011-01-31 Jay Berkenbilt <ejb@ql.org> + + * libqpdf/QPDF.cc (readObjectAtOffset): use -1 rather than 0 when + reading an object at a given to indicate that no object number is + expected. This allows xref recovery to proceed even if a file + uses the invalid object number 0 as a regular object. + + * libqpdf/QPDF_linearization.cc (isLinearized): use -1 rather than + 0 as a sentintel for not having found the first object in the + file. Since -1 can never match the regular expression, this + prevents an infinite loop when checking a file that starts with + (erroneous) 0 0 obj. (Fixes qpdf-Bugs-3159950.) + 2010-10-04 Jay Berkenbilt <ejb@ql.org> * 2.2.2: release |
