MGASA-2021-0357 - Updated tomcat packages fix security vulnerabilities

Publication date: 20 Jul 2021
URL: https://advisories.mageia.org/MGASA-2021-0357.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2021-25122,
     CVE-2021-25329

When responding to new h2c connection requests, Apache Tomcat versions 
9.0.0.M1 to 9.0.41 could duplicate request headers and a limited amount of
request body from one request to another meaning user A and user B could both
see the results of user A's request (CVE-2021-25122).

The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 9.0.0.M1 to
9.0.41 with a configuration edge case that was highly unlikely to be used, the
Tomcat instance was still vulnerable to CVE-2020-9494 (CVE-2021-25329).
