Summary

Important: gzip security update

Details

The gzip packages contain the gzip (GNU zip) data compression utility. gzip is used to compress regular files. It replaces them with files containing the .gz extension, while retaining ownership modes, access, and modification times.

Security Fix(es):

gzip: arbitrary-file-write vulnerability (CVE-2022-1271)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2022-1271 (GCVE-0-2022-1271)

Vulnerability from cvelistv5 – Published: 2022-08-31 15:33 – Updated: 2025-06-09 14:56

Summary

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.

Severity ?

8.8 (High)
