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 remote Fedora 41 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2024-d62088b505 advisory.

  - Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that     uses this library. Starting in version 1.13 and prior to version 3.1.4, Pandoc is susceptible to an     arbitrary file write vulnerability, which 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. This     vulnerability allows an attacker to create or overwrite arbitrary files on the system ,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. The fix is to unescape     the percent-encoding prior to checking that the resource is not above the working directory, and prior to     extracting the extension. Some code for checking that the path is below the working directory was flawed     in a similar way and has also been fixed. Note that the `--sandbox` option, which only affects IO done by     readers and writers themselves, does not block this vulnerability. The vulnerability is patched in pandoc     3.1.4. As a workaround, audit the pandoc command and disallow PDF output and the `--extract-media` option.
