NVDhttps://nvd.nist.gov/vuln/detail/CVE-2022-1271
CWEhttps://cwe.mitre.org/data/definitions/179.html

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

Weakness

The product validates input before applying protection mechanisms that modify the input, which could allow an attacker to bypass the validation via dangerous inputs that only arise after the modification.
