When zgrep is applied on the attacker\u0027s chosen file name (for example, a crafted file name), this can overwrite an attacker\u0027s content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names.
