Arch Linux Security Advisory ASA-202101-36 ========================================== Severity: Medium Date : 2021-01-20 CVE-ID : CVE-2017-8054 CVE-2018-5783 CVE-2018-11254 CVE-2018-11255 CVE-2018-11256 CVE-2018-12982 CVE-2018-14320 CVE-2018-19532 CVE-2018-20751 CVE-2019-9199 CVE-2019-9687 Package : podofo Type : multiple issues Remote : No Link : https://security.archlinux.org/AVG-867 Summary ======= The package podofo before version 0.9.7-1 is vulnerable to multiple issues including arbitrary code execution and denial of service. Resolution ========== Upgrade to 0.9.7-1. # pacman -Syu "podofo>=0.9.7-1" The problems have been fixed upstream in version 0.9.7. Workaround ========== None. Description =========== - CVE-2017-8054 (denial of service) The function PdfPagesTree::GetPageNodeFromArray in PdfPageTree.cpp:464 in PoDoFo 0.9.6 allows remote attackers to cause a denial of service (infinite recursion and application crash) via a crafted PDF document. The issue is fixed in PoDoFo version 0.9.7. - CVE-2018-5783 (denial of service) In PoDoFo 0.9.6, there is an uncontrolled memory allocation in the PoDoFo::PdfVecObjects::Reserve function (base/PdfVecObjects.h). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted pdf file. The issue is fixed in PoDoFo version 0.9.7. - CVE-2018-11254 (denial of service) An issue was discovered in PoDoFo 0.9.6. 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. The issue is fixed in PoDoFo version 0.9.7. - CVE-2018-11255 (denial of service) An issue was discovered in PoDoFo 0.9.6. 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. The issue is fixed in PoDoFo version 0.9.7. - CVE-2018-11256 (denial of service) An issue was discovered in PoDoFo 0.9.6. 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. The issue is fixed in PoDoFo version 0.9.7. - CVE-2018-12982 (denial of service) An 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 issue is fixed in PoDoFo version 0.9.7. - CVE-2018-14320 (arbitrary code execution) This vulnerability in PoDoFo 0.9.6 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. The issue is fixed in PoDoFo version 0.9.7. - CVE-2018-19532 (denial of service) 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. The issue is fixed in PoDoFo version 0.9.7. - CVE-2018-20751 (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 issue is fixed in PoDoFo version 0.9.7. - CVE-2019-9199 (denial of service) 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. The issue is fixed in PoDoFo version 0.9.7. - CVE-2019-9687 (arbitrary code execution) PoDoFo 0.9.6 has a heap-based buffer overflow in PdfString::ConvertUTF16toUTF8 in base/PdfString.cpp. The issue is fixed in PoDoFo version 0.9.7. Impact ====== A maliciously crafted PDF file can crash the application or execute arbitrary code.
