Debian Linux Security Advisory 5314-1 - It was discovered that missing input sanitising in the ctags functionality of Emacs may result in the execution of arbitrary shell commands.
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.
