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.
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 0.9.5. 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 PoDoFo 0.9.5. The function PdfPage::GetPageNumber() in PdfPage.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 0.9.5. 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.
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.
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.
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.
