CVE-2022-45939 Open this link in a new tabHow to fix?
Upgrade RHEL:8 emacs to version 1:26.1-9.el8 or higher.
This issue was patched in RHSA-2023:3042.
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 ctags program. For example, a victim may use the "ctags *" command (suggested in the ctags documentation) in a situation where the current working directory has contents that depend on untrusted input.
