New emacs packages are available for Slackware 15.0 and -current to
fix security issues.

Here are the details from the Slackware 15.0 ChangeLog:

patches/packages/emacs-29.3-i586-1_slack15.0.txz: Upgraded.
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.
For more information, see:

(
Security fix *)
