		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">python-bottle security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for python-bottle is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Bottle is a fast, simple and lightweight WSGI micro web-framework for Python. It is distributed as a single file module and has no dependencies other than the Python Standard Library.

Security Fix(es):

The package bottle from 0 and before 0.12.19 are vulnerable to Web Cache Poisoning by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.(CVE-2020-28473)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for python-bottle is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1.

openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
