Description Guilherme de Almeida Suckevicz 2022-12-14 17:03:09 UTC

A flaw was found in Exuberant Ctags in the way it handles the "-o" option, this option is used to specify the tag filename. A crafted tag filename specified in the command line or in the configuration file results in arbitrary command execution because the externalSortTags() in sort.c calls the system(3) function in an unsafe way.
