------------------------------------------------------------------------- Debian LTS Advisory DLA-4322-1 [email protected] https://www.debian.org/lts/security/ Lukas Mrdian 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:
