ALMALINUX9.2:CLSA-2025:1754650455 advisory.

  - Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Apache Tomcat. This issue affects
    Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through
    9.0.97. The following versions were EOL at the time the CVE was created but are known to be affected:
    8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. The mitigation for CVE-2024-50379
    was incomplete. Users running Tomcat on a case insensitive file system with the default servlet write
    enabled (readonly initialisation parameter set to the non-default value of false) may need additional
    configuration to fully mitigate CVE-2024-50379 depending on which version of Java they are using with
    Tomcat: - running on Java 8 or Java 11: the system property sun.io.useCanonCaches must be explicitly set
    to false (it defaults to true) - running on Java 17: the system property sun.io.useCanonCaches, if set,
    must be set to false (it defaults to false) - running on Java 21 onwards: no further configuration is
    required (the system property and the problematic cache have been removed) Tomcat 11.0.3, 10.1.35 and
    9.0.99 onwards will include checks that sun.io.useCanonCaches is set appropriately before allowing the
    default servlet to be write enabled on a case insensitive file system. Tomcat will also set
    sun.io.useCanonCaches to false by default where it can. (CVE-2024-56337)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
