  script_tag(name:"insight", value:"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. (CVE-2022-48337)

An issue was discovered in GNU Emacs through 28.2. In ruby-mode.el, the
ruby-find-library-file function has a local command injection
vulnerability. The ruby-find-library-file function is an interactive
function, and bound to C-c C-f. Inside the function, the external command
gem is called through shell-command-to-string, but the feature-name
parameters are not escaped. Thus, malicious Ruby source files may cause
commands to be executed. (CVE-2022-48338)

An issue was discovered in GNU Emacs through 28.2. htmlfontify.el has a
command injection vulnerability. In the hfy-istext-command function, the
parameter file and parameter srcdir come from external input, and
parameters are not escaped. If a file name or directory name contains
shell metacharacters, code may be executed. (CVE-2022-48339)");
