Alpine: multiple zlib packages: security update to 1.2.11-r4

critical Tenable Cloud Security Plugin ID 424735

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many
distant matches. (CVE-2018-25032)

- zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a
large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some
common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g.,
see the nodejs/node reference). (CVE-2022-37434)
