        "Description": "This update upgrades podofo to version 0.9.7-alt1. \nSecurity Fix(es):\n\n * BDU:2019-02839: Уязвимость функции crop_page() программной библиотеки PoDoFo, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2022-01664: Уязвимость функции IsNextToken компонента src/base/PdfToenizer.cpp программной библиотеки для работы с PDF PoDoFo, позволяющая нарушителю получить доступ к конфиденциальным данным\n\n * BDU:2022-01797: Уязвимость компонента src/base/PdfDictionary.cpp программной библиотеки для работы с PDF PoDoFo, позволяющая нарушителю вызвать отказ в обслуживании\n\n * CVE-2018-19532: 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.\n\n * CVE-2018-20751: An issue was discovered in crop_page in PoDoFo 0.9.6. For a crafted PDF document, pPage-\u003eGetObject()-\u003eGetDictionary().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.\n\n * CVE-2018-20797: 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.\n\n * CVE-2019-10723: 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.\n\n * CVE-2019-20093: 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.\n\n * CVE-2019-9199: 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.\n\n * CVE-2019-9687: PoDoFo 0.9.6 has a heap-based buffer overflow in PdfString::ConvertUTF16toUTF8 in base/PdfString.cpp.\n\n * CVE-2020-18971: 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'.\n\n * CVE-2020-18972: 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'.",
