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 tofalse (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.
