We have documented the API for parsing DIB and GIF images. Print(' Page:', i + 1, '- Object:', obj.ObjectToString(objtable, pages.at(i)))

We introduced SDK support for parsing the pages in a PDF: Pdf.EnableFilter(PDFObject.FilterType_JPXDecode, False) Pdf.EnableFilter(PDFObject.FilterType_DCTDecode, False) We want to thank Dénes for his research and for providing us with his proof of concept!įor the customers of our engine: in case you are not interested in supporting these filters, we have introduced a mechanism to individually disable filters: It has been done as a proof of concept by Dénes Olivér Óvári and we’ll detail this in the next release of our e-zine. The reason for this is that it is possible to encode a JavaScript script using a grayscale JPEG image. What it means is that we convert images compressed in JPEG to raw data when decoding streams. These two filters represent JPEG and JPEG2000 respectively. We added support for /DCTDecode and /JPXDecode filters in PDFs.

Therefore, now the library is being run again in the same process and it’s even faster than before.įor the customers of our engine: it is still possible to use the old JBIG2 library:īy default version 2 (the new library) is used. Not only is it faster than the previous one, but it also has constraints on allocation and processing time by default. This release features a completely rewritten JBIG2 library. In a recent release we made our already hardened JBIG2 decoding support even more secure by relegating it to a different process and constraining it to a time threshold. The exploit mentioned in the article creates over 70,000 segments to create a small virtual machine in logical operations defined by JBIG2. In fact, one of the most sophisticated exploits has been created exploiting a JBIG2 library in iOS. JBIG2 is an imperative file format which has been demonstrated can be Turing complete. Our PDF support has been featuring the capability to decode JBIG2 streams for many years. This release contains many improvements to our PDF support. We’re happy to announce the release of Cerbero Suite 6.1 and Cerbero Engine 3.1!
