Debian 11: DLA-4322-1 log4cxx Critical HTML JSON Injection CVE-2025-54812

Multiple vulnerabilities were discovered in log4cxx, a logging library for C++ that is compatible with the JAVA log4j framework. CVE-2025-54812 . ------------------------------------------------------------------------- Debian LTS Advisory DLA-4322-1 This email address is being protected from spambots. You need JavaScript enabled to view it. https://www.debian.org/lts/security/ Lukas Märdian October 05, 2025 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : log4cxx Version : 0.11.0-2+deb11u1 CVE ID : CVE-2025-54812 CVE-2025-54813 Debian Bug : 1111879 1111881 Multiple vulnerabilities were discovered in log4cxx, a logging library for C++ that is compatible with the JAVA log4j framework. CVE-2025-54812 When using HTMLLayout, logger names are not properly escaped when writing out to the HTML file. If untrusted data is used to retrieve the name of a logger, an attacker could theoretically inject HTML or Javascript in order to hide information from logs or steal data from the user. CVE-2025-54813 When using JSONLayout, not all payload bytes are properly escaped. If an attacker-supplied message contains certain non-printable characters, these will be passed along in the message and written out as part of the JSON message. This may prevent applications that consume these logs from correctly interpreting the information within them. For Debian 11 bullseye, these problems have been fixed in version 0.11.0-2+deb11u1. We recommend that you upgrade your log4cxx packages. For the detailed security status of log4cxx please refer to its security tracker page at: https://security-tracker.debian.org/tracker/source-package/log4cxx Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS .
