Name of the Vulnerable Software and Affected Versions linenoise (affected versions not specified)

Description A time-of-check to time-of-use (TOCTOU) issue exists in the linenoiseHistorySave function within the linenoise library. This flaw allows local attackers to overwrite arbitrary files and modify permissions by exploiting a symlink race condition.
