Publication date: 10 Jan 2021
URL: https://advisories.mageia.org/MGASA-2021-0020.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-17527

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.
