CVE-2022-1271

An arbitrary file write vulnerability was found in GNU gzip’s zgrep
utility. When zgrep is applied on the attacker’s chosen file name (for
example, a crafted file name), this can overwrite an attacker’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.
