PoDoFo Project PoDoFo 0.9.6

PoDoFo 0.9.6 has a heap-based buffer overflow in PdfString::ConvertUTF16toUTF8 in base/PdfString.cpp.

PoDoFo::Impose::PdfTranslator::setSource() in pdftranslator.cpp in PoDoFo 0.9.6 has a NULL pointer dereference that can (for example) be triggered by sending a crafted PDF file to the podofoimpose binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.

A NULL pointer dereference vulnerability exists in the function PdfTranslator::setTarget() in pdftranslator.cpp of PoDoFo 0.9.6, while creating the PdfXObject, as demonstrated by podofoimpose. It allows an attacker to cause Denial of Service.

An issue was discovered in crop_page in PoDoFo 0.9.6. For a crafted PDF document, pPage->GetObject()->GetDictionary().AddKey(PdfName("MediaBox"),var) can be problematic due to the function GetObject() being called for the pPage NULL pointer object. The value of pPage at this point is 0x0, which causes a NULL pointer dereference.

A stack-based buffer over-read in the PdfEncryptMD5Base::ComputeEncryptionKey() function in PdfEncrypt.cpp in PoDoFo 0.9.6-rc1 could be leveraged by remote attackers to cause a denial-of-service via a crafted pdf file.

An issue was discovered in PoDoFo 0.9.6. There is an attempted excessive memory allocation in PoDoFo::podofo_calloc in base/PdfMemoryManagement.cpp when called from PoDoFo::PdfPredictorDecoder::PdfPredictorDecoder in base/PdfFiltersPrivate.cpp.

The PoDoFo::PdfVariant::DelayedLoad function in PdfVariant.h in PoDoFo 0.9.6 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file, because of ImageExtractor.cpp.

Invalid memory read in the PoDoFo::PdfVariant::DelayedLoad() function in PdfVariant.h in PoDoFo 0.9.6-rc1 allows remote attackers to have denial-of-service impact via a crafted file.

An issue was discovered in PoDoFo 0.9.6. The PdfPagesTreeCache class in doc/PdfPagesTreeCache.cpp has an attempted excessive memory allocation because nInitialSize is not validated.

Exposure of Sensitive Information to an Unauthorized Actor in PoDoFo v0.9.6 allows attackers to obtain sensitive information via 'IsNextToken' in the component 'src/base/PdfToenizer.cpp'.

Stack-based Buffer Overflow in PoDoFo v0.9.6 allows attackers to cause a denial of service via the component 'src/base/PdfDictionary.cpp:65'.
