2021-07-20 CVE-2021-36978 Out-of-bounds Write vulnerability in Qpdf Project Qpdf
QPDF 9.x through 9.1.1 and 10.x through 10.0.4 has a heap-based buffer overflow in Pl_ASCII85Decoder::write (called from Pl_AES_PDF::flush and Pl_AES_PDF::finish) when a certain downstream write fails.
4.3
2018-10-06 CVE-2018-18020 Uncontrolled Recursion vulnerability in Qpdf Project Qpdf 8.2.1
In QPDF 8.2.1, in libqpdf/QPDFWriter.cc, QPDFWriter::unparseObject and QPDFWriter::unparseChild have recursive calls for a long time, which allows remote attackers to cause a denial of service via a crafted PDF file.
4.3
2018-04-10 CVE-2018-9918 Uncontrolled Recursion vulnerability in multiple products
libqpdf.a in QPDF through 8.0.2 mishandles certain "expected dictionary key but found non-name object" cases, allowing remote attackers to cause a denial of service (stack exhaustion), related to the QPDFObjectHandle and QPDF_Dictionary classes, because nesting in direct objects is not restricted.
