Security Fix(es): An arbitrary file write vulnerability was found in GNU gzip_x27;s zgrep utility. When zgrep is applied on the attacker_x27;s chosen file name (for example, a crafted file name), this can overwrite an attacker_x27;s 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. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.
