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.
