		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">python-gunicorn security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for python-gunicorn is now available for openEuler-24.03-LTS-SP1</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Gunicorn(Green Unicorn) is a Python WSGI HTTP Server for UNIX. It&amp;apos;s a pre-fork worker model ported from Ruby&amp;apos;s Unicorn_ project. The Gunicorn server is broadly compatible with various web frameworks, simply implemented, light on server resource usage, and fairly speedy.

Security Fix(es):

Gunicorn version 21.2.0 does not properly validate the value of the &apos;Transfer-Encoding&apos; header as specified in the RFC standards, which leads to the default fallback method of &apos;Content-Length,&apos; making it vulnerable to TE.CL request smuggling. This vulnerability can lead to cache poisoning, data exposure, session manipulation, SSRF, XSS, DoS, data integrity compromise, security bypass, information leakage, and business logic abuse.(CVE-2024-6827)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for python-gunicorn is now available for openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP3/openEuler-24.03-LTS-SP1.
