Alpine: gzip: security update to 1.12-r0

high Tenable Self-Hosted Container Security Plugin ID 404851

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2022-1271)
