✅ Remediation

Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 Workaround: This issue can be mitigated by removing the ISO-2022-CN-EXT from glibc-gconv-extra's modules configuration. This can be done by: 1) Verify if the module is loaded by running: ~~~ $ iconv -l | grep -E 'CN-?EXT' ISO-2022-CN-EXT// ISO2022CNEXT// ~~~ If the grep output looks like the above, ISO-2022-CN-EXT module is enabled. 2) Disabled the module by editing the file located at /usr/lib64/gconv/gconv-modules.d/gconv-modules-extra.conf and comment the following lines. For RHEL 7 the file that needs to be edited is /usr/lib64/gconv/gconv-modules. This step requires to be executed by a privileged user: ~~~ # from to module cost alias ISO2022CNEXT// ISO-2022-CN-EXT// module ISO-2022-CN-EXT// INTERNAL ISO-2022-CN-EXT 1 module INTERNAL ISO-2022-CN-EXT// ISO-2022-CN-EXT 1 ~~~ For commenting those lines just add the '#' character at the beginning of mentioned lines: ~~~ # from to module cost #alias ISO2022CNEXT// ISO-2022-CN-EXT// #module ISO-2022-CN-EXT// INTERNAL ISO-2022-CN-EXT 1 #module INTERNAL ISO-2022-CN-EXT// ISO-2022-CN-EXT 1 ~~~ 3) Update the iconv cache by running: ~~~ sudo iconvconfig ~~~ 4) Check if the module was disabled by running the first step again. This time ISO-2022-CN-EXT should not appear in the output. Please notice that disabling the mentioned gconv module may lead applications relying in the affected module to fail in converting characters and should be used as a temporary mitigation before being able to fully update the affected package. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
