m-holger	c02cb9a720	Fix QPDF::recoverStreamLength ... Ensure the the recovered stream end is not part of a different object. Test file is bad24.pdf with stream 4 'endstream' corrupted.	2024-08-20 15:14:01 +01:00

m-holger	f2228b1f88	Fix handling of hybrid reference files in QPDF::read_xrefTable ... QPDF::read_xrefTable ignores type 0 entries for objects in a section if an associates XRefStm has an entry for the same object. The spec states: When the conforming reader searches for an object, if an entry is not found in any given standard cross-reference section, the search shall proceed to a cross-reference stream specified by the XRefStm entry before looking in the previous cross-reference section, If a deleted entry is found in a section, the XRefStm is not searched according to the standard.	2024-08-16 15:58:55 +01:00

m-holger	08eb6844c7	Add new qpdf_fuzzer test cases	2024-08-06 12:26:37 +01:00
m-holger	06001ed25b	Refactor the creation of unresolved objects ... Create unresolved objects only for objects in the xref table (except during parsing of the xref table). Do not add indirect nulls into the the object cache as the result of a cache miss during a call to getObject except during parsing or creation/updating from JSON. To support this behaviour, add new private methods getObjectForParser and getObjectForJSON. As a result of this change, dangling references are treated as direct nulls rather than indirect nulls.	2024-08-06 12:22:09 +01:00
m-holger	87ee8ad071	In QPDFParser constructor add add parameter parse_pdf ... Prepare for treating indirect references differently depending on whether we are parsing a PDF file (in which case reference to objects not in the xref table are null even if they are in the object cache) or whether parse from user code (in which case an indirect reference can refer to a user created object).	2024-08-06 10:02:07 +01:00
