Package        : tomcat8
Version        : 8.5.54-0+deb9u6
CVE ID         : CVE-2021-24122 CVE-2021-25122 CVE-2021-25329

Three security issues have been detected in tomcat8.

CVE-2021-24122

    When serving resources from a network location using the NTFS file system,
    Apache Tomcat versions 8.5.0 to 8.5.59 is susceptible to JSP source code
    disclosure in some configurations. The root cause was the unexpected
    behaviour of the JRE API File.getCanonicalPath() which in turn was caused
    by the inconsistent behaviour of the Windows API (FindFirstFileW) in some
    circumstances.

CVE-2021-25122

    When responding to new h2c connection requests, Apache Tomcat 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-2021-25329

    The fix for 2020-9484 was incomplete. When using Apache Tomcat 8.5.0 to
    8.5.61 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.

For Debian 9 stretch, these problems have been fixed in version
8.5.54-0+deb9u6.

We recommend that you upgrade your tomcat8 packages.
