Description

Updated podofo packages fix security vulnerability The updated packages fix security vulnerabilities: 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. (CVE-2018-12983) 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. (CVE-2018-20751) 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. (CVE-2019-9199) PoDoFo 0.9.6 has a heap-based buffer overflow in PdfString::ConvertUTF16toUTF8 in base/PdfString.cpp. (CVE-2019-9687) 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. (CVE-2019-20093)
