Synopsis
The remote Debian host is missing one or more security-related updates.Description
The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3548 advisory.- 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. (CVE-2018-18020)
- An issue was discovered in QPDF version 10.0.4, allows remote attackers to execute arbitrary code via crafted .pdf file to Pl_ASCII85Decoder::write parameter in libqpdf. (CVE-2021-25786)
- 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. (CVE-2021-36978)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade the qpdf packages.For Debian 10 buster, these problems have been fixed in version 8.4.0-2+deb10u1.
