How to fix?

Upgrade RHEL:8 emacs to version 1:26.1-7.el8_6.3 or higher.
This issue was patched in RHSA-2024:1103.

NVD Description

Note: Versions mentioned in the description apply only to the upstream emacs package and not the emacs package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the etags program. For example, a victim may use the "etags -u *" command (suggested in the etags documentation) in a situation where the current working directory has contents that depend on untrusted input.
