REDHAT-BUG-2171987
First published: Tue Feb 21 2023(Updated: )
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. <a href="https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=01a4035c869b91c153af9a9132c87adb7669ea1c">https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=01a4035c869b91c153af9a9132c87adb7669ea1c</a>
