Package        : tomcat10
CVE ID         : CVE-2024-34750 CVE-2024-38286 CVE-2024-50379 CVE-2024-52316
                 CVE-2024-54677 CVE-2024-56337

Several problems have been addressed in Tomcat 10, a Java based web server,
servlet and JSP engine which may lead to a denial-of-service.


CVE-2024-38286

    Apache Tomcat, under certain configurations, allows an attacker to cause an
    OutOfMemoryError by abusing the TLS handshake process.

CVE-2024-52316

    Unchecked Error Condition vulnerability in Apache Tomcat. If Tomcat is
    configured to use a custom Jakarta Authentication (formerly JASPIC)
    ServerAuthContext component which may throw an exception during the
    authentication process without explicitly setting an HTTP status to
    indicate failure, the authentication may not fail, allowing the user to
    bypass the authentication process. There are no known Jakarta
    Authentication components that behave in this way.

CVE-2024-50379 / CVE-2024-56337

    Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability during JSP
    compilation in Apache Tomcat permits an RCE on case insensitive file
    systems when the default servlet is enabled for write (non-default
    configuration).
    Some users may need additional configuration to fully mitigate
    CVE-2024-50379 depending on which version of Java they are using with
    Tomcat. For Debian 12 "bookworm" the system property
    sun.io.useCanonCaches must be explicitly set to false (it defaults to
    false). Most Debian users will not be affected because Debian uses case
    sensitive file systems by default.

CVE-2024-34750

    Improper Handling of Exceptional Conditions, Uncontrolled Resource
    Consumption vulnerability in Apache Tomcat. When processing an HTTP/2
    stream, Tomcat did not handle some cases of excessive HTTP headers
    correctly. This led to a miscounting of active HTTP/2 streams which in turn
    led to the use of an incorrect infinite timeout which allowed connections
    to remain open which should have been closed.

CVE-2024-54677

    Uncontrolled Resource Consumption vulnerability in the examples web
    application provided with Apache Tomcat leads to denial of service.


For the stable distribution (bookworm), these problems have been fixed in
version 10.1.34-0+deb12u1.

We recommend that you upgrade your tomcat10 packages.
