Pandoc before 3.1.6 allows arbitrary file write: this can be triggered by providing a crafted image element in the input when generating files via the --extract-media option or outputting to PDF format. This allows an attacker to create or overwrite arbitrary files, depending on the privileges of the process running Pandoc. It only affects systems that pass untrusted user input to Pandoc and allow Pandoc to be used to produce a PDF or with the --extract-media option. NOTE: this issue exists because of an incomplete fix for CVE-2023-35936 (failure to properly account for double encoded path names).

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    Package        : pandoc     Version        : 2.2.1-3+deb10u1     CVE ID         : CVE-2023-35936 CVE-2023-38745     Debian Bug     : 1041976

    Arbitrary file write vulnerabilities were discovered in pandoc, an     Haskell library and CLI tool for converting from one markup format to     another.  These vulnerabilities can be triggered by providing a     specially crafted image element in the input when generating files using     the `--extract-media` option or outputting to PDF format, and allow an     attacker to create or overwrite arbitrary files on the system (depending     on the privileges of the process running pandoc).

    CVE-2023-35936

        Entroy C discovered that appending percent-encoded directory         components to the end of malicious data: URI, an attacker could         trick pandoc into creating or or overwriting arbitrary files on the         system.

    CVE-2023-38745

        I discovered that the upstream fix for CVE-2023-35936 was         incomplete, namely that the vulnerability remained when encoding '%'         characters as '%25'.

    For Debian 10 buster, these problems have been fixed in version     2.2.1-3+deb10u1.

    We recommend that you upgrade your pandoc packages.

    For the detailed security status of pandoc please refer to     its security tracker page at:
