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 m_offsets.size.

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

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 m_offsets.size.

In PoDoFo 0.9.5, there exists an infinite loop vulnerability in PdfParserObject::ParseFileComplete() in PdfParserObject.cpp which may result in stack overflow. Remote attackers could leverage this vulnerability to cause a denial-of-service or possibly unspecified other impact via a crafted pdf file.

In PoDoFo 0.9.5, there exists a heap-based buffer overflow vulnerability in PoDoFo::PdfTokenizer::GetNextToken() in PdfTokenizer.cpp, a related issue to CVE-2017-5886. Remote attackers could leverage this vulnerability to cause a denial-of-service or potentially execute arbitrary code via a crafted pdf file.

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.

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.

Podofo v0.10.0 was discovered to contain a heap buffer overflow via the component PoDoFo::PdfEncryptRC4::PdfEncryptRC4.

Podofo v0.10.0 was discovered to contain a heap buffer overflow via the component PoDoFo::PdfEncryptAESV3::PdfEncryptAESV3.

Podofo v0.10.0 was discovered to contain a heap-use-after-free via the component PoDoFo::PdfEncrypt::IsMetadataEncrypted().

podofoinfo 0.10.0 was discovered to contain a segmentation violation via the function PoDoFo::PdfDictionary::findKeyParent.

A heap-use-after free in the PdfTokenizer::ReadDictionary function of podofo v0.10.0 to v0.10.5 allows attackers to cause a Denial of Service (DoS) by supplying a crafted PDF file. NOTE: this is disputed by the Supplier because there is no available file to reproduce the issue.

Heap-based buffer overflow in the PoDoFo::PdfTokenizer::GetNextToken function in PdfTokenizer.cpp in PoDoFo 0.9.4 allows remote attackers to have unspecified impact via a crafted file.

Heap-based buffer overflow in the PoDoFo::PdfVariant::DelayedLoad function in PdfVariant.h in PoDoFo 0.9.4 allows remote attackers to have unspecified impact via a crafted file.

Buffer overflow in the PoDoFo::PdfParser::ReadXRefSubsection function in PdfParser.cpp in PoDoFo 0.9.4 allows remote attackers to have unspecified impact via a crafted file.

PoDoFo 0.9.5 does not properly validate memcpy arguments in the PdfMemoryOutputStream::Write function (base/PdfOutputStream.cpp). Remote attackers could leverage this vulnerability to cause a denial-of-service or possibly unspecified other impact via a crafted pdf file.

Integer overflow in base/PdfParser.cpp in PoDoFo 0.9.4 allows remote attackers to have unspecified impact via a crafted file.

In PoDoFo 0.9.5, there exists a heap-based buffer over-read vulnerability in UnescapeName() in PdfName.cpp. Remote attackers could leverage this vulnerability to cause a denial-of-service or possibly unspecified other impact via a crafted pdf file.

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.

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.

The function TextExtractor::ExtractText in TextExtractor.cpp:77 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.

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.

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.

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.

podofoinfo 0.10.0 was discovered to contain a segmentation violation via the function PoDoFo::PdfObject::DelayedLoad.
