SCA: security update for org.apache.logging.log4j:log4j-1.2-api (GHSA-h383-gmxw-35v2)

medium Tenable Cloud Security Plugin ID 440329

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The Log4j1XmlLayout from the Apache Log4j 1-to-Log4j 2 bridge fails to escape characters forbidden by the
 XML 1.0 standard, producing malformed XML output. Conforming XML parsers are required to reject documents
 containing such characters with a fatal error, which may cause downstream log processing systems to drop
 or fail to index affected records. Two groups of users are affected: * Those using Log4j1XmlLayout
 directly in a Log4j Core 2 configuration file. * Those using the Log4j 1 configuration compatibility layer
 with org.apache.log4j.xml.XMLLayout specified as the layout class. Users are advised to upgrade to Apache
 Log4j 1-to-Log4j 2 bridge version 2.25.4, which corrects this issue. Note: The Apache Log4j 1-to-Log4j 2
 bridge is deprecated and will not be present in Log4j 3. Users are encouraged to consult the Log4j 1 to
 Log4j 2 migration guide https://logging.apache.org/log4j/2.x/migrate-from-log4j1.html , and specifically
 the section on eliminating reliance on the bridge. (CVE-2026-34479)

Solution

Update the org.apache.logging.log4j:log4j-1.2-api library and its related packages to version 2.25.4 or later.
