Summary

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.

its security tracker page at:
