9、C 21000-10:2006/Amd.1:2006(E) ISO/IEC 2006 All rights reserved iii Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC parti
10、cipate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmenta
11、l and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
12、The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodie
13、s casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 1 to ISO/IEC 21000-10:2006 was prepared by Joint Technical Commit
14、tee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. This Amendment defines normative C+ bindings for Digital Item Base Operations, informative security and platform dependence considerations, an informative example of a safe

18、e, add at the end: C+ bindings for Digital Item Base Operations: Annex E specifies the C+ bindings for the Digital Item Base Operations described in 5.4. In Clause 2, Normative references, insert the following normative reference before the reference to ISO/IEC 16262:2002: ISO/IEC 14882:2003, Progra

20、.2 C+ bindings The use of the C+ DIBO bindings can potentially result in security issues. 5.6.1.3 DOM Load and Save The DOM Load and Save API exposes potential security issues, because they provide access to the file system.

22、2.1 Execute DIBO The use of the DIP.execute DIBO can result in the use of platform dependent code. It is possible to avoid those issues by creating a profile removing DIP.execute. This can be done using profiles as demonstrated in subclause Annex I.8. 5.6.2.2 C+ bindings The use of the C+ DIBO bindi
23、ngs will result in the use of platform dependent code. It is possible to avoid those issues by creating a profile removing the C+ bindings. This can be done using profiles as demonstrated in subclause Annex I.8. Adjust numbering clauses: “5.6 Digital Item eXtension Operations“ numbering change to “5
24、.7 Digital Item eXtension Operations“ numbering. And change following (sub)clauses numbering accordingly. Add a new Annex E: Annex E (normative) C+ bindings for Digital Item Base Operations E.1 Introduction C+ bindings for DIBOs are specified so that C+ executables can interact with the DIP environm
25、ent. The way in which C+ executables are executed and the reference to the bindings are obtained, is done in an implementation specific way.
