------------------------------------------------------------------------- Debian LTS Advisory DLA-4017-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Markus Koschany January 17, 2025 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : tomcat9 Version : 9.0.43-2~deb11u11 CVE ID : CVE-2024-21733 CVE-2024-38286 CVE-2024-50379 CVE-2024-52316 CVE-2024-56337 Several problems have been addressed in Tomcat 9, a Java based web server, servlet and JSP engine which may lead to a denial-of-service or the disclosure of sensitive information. CVE-2024-21733 Generation of Error Message Containing Sensitive Information vulnerability in Apache Tomcat. 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 11 "bullseye" the system property sun.io.useCanonCaches must be explicitly set to false (it defaults to true). Most Debian users will not be affected because Debian uses case sensitive file systems by default. For Debian 11 bullseye, these problems have been fixed in version 9.0.43-2~deb11u11. We recommend that you upgrade your tomcat9 packages.
