-------------------------------------------------------------------------------- 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:
