https://notcve.org/view.php?id=CVE-2023-38745
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). • https://github.com/jgm/pandoc/commit/eddedbfc14916aa06fc01ff04b38aeb30ae2e625 https://github.com/jgm/pandoc/compare/3.1.5...3.1.6 https://lists.debian.org/debian-lts-announce/2023/07/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JGRJHU2FTSGTHHRTNDF7STEKLKKA25JN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LYP3FKDS3KAYMQUZVVL73IUI4CWSKLKP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.o •
CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 1CVE-2023-35936 – Arbitrary file write is possible in Pandoc when using PDF output or --extract-media with untrusted input
https://notcve.org/view.php?id=CVE-2023-35936
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. • https://github.com/jgm/pandoc/security/advisories/GHSA-xj5q-fv23-575g https://lists.debian.org/debian-lts-announce/2023/07/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/JGRJHU2FTSGTHHRTNDF7STEKLKKA25JN https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LYP3FKDS3KAYMQUZVVL73IUI4CWSKLKP https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/QI6RBP6ZKVC2OOCV6SU2FUHPMAXDDJFU • CWE-20: Improper Input Validation •
