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.
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.
An issue was discovered in PoDoFo 0.9.6. There is an attempted excessive memory allocation in PoDoFo::podofocalloc in base/PdfMemoryManagement.cpp when called from PoDoFo::PdfPredictorDecoder::PdfPredictorDecoder in base/PdfFiltersPrivate.cpp.
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.
In PoDoFo 0.9.5, there is an integer overflow in the PdfXRefStreamParserObject::ParseStream function (base/PdfXRefStreamParserObject.cpp). Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted pdf file.
An issue was discovered in PoDoFo 0.9.5. There is an Excessive Recursion in the PdfPagesTree::GetPageNode() function of PdfPagesTree.cpp. Remote attackers could leverage this vulnerability to cause a denial of service through a crafted pdf file, a related issue to CVE-2017-8054.
An issue was discovered in croppage 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.
An issue was discovered in PoDoFo 0.9.5. The function PdfDocument::Append() in PdfDocument.cpp in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PDF document.
Heap-based buffer overflow in the PdfParser::ReadXRefSubsection function in base/PdfParser.cpp in PoDoFo allows attackers to have unspecified impact via vectors related to moffsets.size.
The PoDoFo::PdfXRefStreamParserObject::ReadXRefStreamEntry function in base/PdfXRefStreamParserObject.cpp:224 in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted PDF file.
Heap-based buffer overflow in the PdfParser::ReadObjects function in base/PdfParser.cpp in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via vectors related to moffsets.size.
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.
This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of PoDoFo. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within PdfEncoding::ParseToUnicode. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-5673.
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.
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.
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'.
A flaw was found in PoDoFo 0.9.7. An use-after-free in PoDoFo::PdfVecObjects::Clear() function can cause a denial of service via a crafted PDF file.
A flaw was found in PoDoFo 0.9.7. A stack-based buffer overflow in PdfEncryptMD5Base::ComputeOwnerKey function in PdfEncrypt.cpp is possible because of a improper check of the keyLength value.
