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.

According to the versions of the emacs package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - 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.
