How to fix?

Upgrade SLES:15.0 tomcat-servlet-4_0-api to version 9.0.36-3.79.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-servlet-4_0-api package and not the tomcat-servlet-4_0-api package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.
