Category: wxpdfdoc Group: last released version Status: Open Resolution: None Priority: 5 Private: No Submitted By: Eric W Savage (ewsavage) Assigned to: Nobody/Anonymous (nobody) Summary: Problem with encrypted documents written by wxpdfdoc Initial Comment: There is a problem with some encrypted PDF documents written by wxpdfdoc. If a PDF document is written after using the SetProtection method with a empty user password and non-empty owner password, then a small percentage of documents require an open password from Adobe Reader to read the document. I took a look through the code and it looks to be an invalid document id written into the trailer section of the PDF. The document id is invalid if it contains a NULL character anywhere before the end of the string. If the document id contains any NULL characters, then the document id is chopped at that point. The chopping is a result of using strcpy. I am using the non UNICODE version of the tool and AES encryption with 128 bits. The offending code is located in the method: wxPdfDocument::OutHexTextstring within the file src/pdfkernel.cpp around line 2083. 2083: #else 2084: strcpy(&mbstr[ofs],s.c_str()); 2085: #endif should probably be: 2083: #else 2084: memcpy(&mbstr[ofs],s.c_str(), len); 2085: #endi ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=462816&aid=2524288&group_id=51305 ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ wxCode-users mailing list wxCode-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wxcode-users
