libservlet3.0-java: The fix for CVE-2020-9484 was incomplete
CVE-2021-25329 is fixed in 9 products on 1 platform, first by libservlet3.0-java 7.0.78-1ubuntu0.1~esm1, released March 1, 2021. It is not reported as exploited. Patch Radar priority: Routine.
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.
