Updated tomcat packages fix security vulnerability

Publication date: 10 Jan 2021
Modification date: 10 Jan 2021
Type: security
Affected Mageia releases : 7
CVE: CVE-2020-17527

Description

While investigating Apache issue 64830 it was discovered that Apache Tomcat
could re-use an HTTP request header value from the previous stream received on
an HTTP/2 connection for the request associated with the subsequent stream.
While this would most likely lead to an error and the closure of the HTTP/2
connection, it is possible that information could leak between requests
(CVE-2020-17527).

The tomcat package has been updated to version 9.0.39, and patched to fix
this issue.
