Debian 11 DSA-5265-1 Critical: Tomcat9 Concurrency Issue

Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine. CVE-2021-43980 . -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5265-1 This email address is being protected from spambots. You need JavaScript enabled to view it. https://www.debian.org/security/ Markus Koschany October 29, 2022 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : tomcat9 CVE ID : CVE-2021-43980 CVE-2022-23181 CVE-2022-29885 Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine. CVE-2021-43980 The simplified implementation of blocking reads and writes introduced in Tomcat 10 and back-ported to Tomcat 9.0.47 onwards exposed a long standing (but extremely hard to trigger) concurrency bug that could cause client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client. CVE-2022-23181 The fix for bug CVE-2020-9484 introduced a time of check, time of use vulnerability into Apache Tomcat that allowed a local attacker to perform actions with the privileges of the user that the Tomcat process is using. This issue is only exploitable when Tomcat is configured to persist sessions using the FileStore. CVE-2022-29885 The documentation of Apache Tomcat for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks. For the stable distribution (bullseye), these problems have been fixed in version 9.0.43-2~deb11u4. We recommend that you upgrade your tomcat9 packages. For the detailed security status oftomcat9 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/source-package/tomcat9 Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: This email address is being protected from spambots. You need JavaScript enabled to view it. . Critical vulnerabilities affecting Tomcat9 have been identified, necessitating immediate patches. Detailed information on the remedies can be found in the Debian advisory DSA-5266-1.. Tomcat Update, Debian Advisory, Servlet Engine Issues. . Severity: Critical. LinuxSecurity.com Team
