Synopsis

The remote Amazon Linux 2 host is missing a security update.

The version of zlib installed on the remote host is prior to 1.2.7-19. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1772 advisory.

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