-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-31a8569c4b 2026-07-18 00:27:50.464532+00:00 -------------------------------------------------------------------------------- Name : log4cxx Product : Fedora 43 Version : 1.7.0 Release : 2.fc43 URL : http://logging.apache.org/log4cxx/index.html Summary : A port to C++ of the Log4j project Description : Log4cxx is a popular logging package written in C++. One of its distinctive features is the notion of inheritance in loggers. Using a logger hierarchy it is possible to control which log statements are output at arbitrary granularity. This helps reduce the volume of logged output and minimize the cost of logging. -------------------------------------------------------------------------------- Update Information: Update to log4cxx 1.7.0. Fixes CVE-2026-40023: XMLLayout did not escape characters forbidden by the XML 1.0 specification, which could cause conforming XML parsers to reject the produced document, silently dropping log records. No ABI-relevant changes; liblog4cxx SONAME (%{sover}) is unchanged. -------------------------------------------------------------------------------- ChangeLog: * Fri Jul 3 2026 Till Hofmann <thofmann@fedoraproject.org> - 1.7.0-2 - Skip 2GB-message test on 32-bit architectures * Fri May 22 2026 Till Hofmann <thofmann@fedoraproject.org> - 1.7.0-1 - Update to 1.7.0 * Fri Jan 16 2026 Fedora Release Engineering <releng@fedoraproject.org> - 1.6.1-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_44_Mass_Rebuild -------------------------------------------------------------------------------- References: [ 1 ] Bug #2457923 - CVE-2026-40023 log4cxx: Apache Log4cxx: Log processing impairment due to unsanitized XML characters [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=2457923 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
