Python vulnerability analysis and mitigation
Overview
A denial of service vulnerability was discovered in markdown-it-py versions prior to v2.2.0. The vulnerability affects the command line interface of the software when processing invalid UTF-8 characters as input (MITRE CVE, NVD).
Technical details
The vulnerability exists in the command line interface's file parsing functionality where the software fails to properly handle invalid UTF-8 characters in input files. The issue was fixed by adding proper UTF-8 encoding handling with error ignoring in the file opening operation (GitHub Commit).
Impact
When exploited, this vulnerability could cause the command line interface to crash, resulting in a denial of service condition if an attacker is allowed to supply input with invalid UTF-8 characters (MITRE CVE).
Mitigation and workarounds
Users should upgrade to markdown-it-py version 2.2.0 or later which includes the fix for this vulnerability. The fix implements proper UTF-8 encoding handling with error ignoring when opening files (GitHub Commit).
