Debian 10 Buster: DLA-3851-1 Critical Gunicorn Request Smuggling

By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn’s handling of Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability allows for a range of attacks including cache poisoning, session manipulation, and data exposure. For Debian 10 buster, this problem has been fixed in version 19.9.0-1+deb10u1. We recommend that you upgrade your gunicorn packages. For the detailed security status of gunicorn please refer to its security tracker page at: https://security-tracker.debian.org/tracker/source-package/gunicorn Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS . Debian LTS Advisory DLA-3852-2 pertains to vulnerabilities in flask. Users areadvised to apply updates to ensure system safety.. Gunicorn, HTTP Server, Request Smuggling, Security Update, Debian. .
