QID 354505: Amazon Linux Security Advisory for gzip, xz : ALAS2022-2022-058

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. (
