Synopsis

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

Description

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 ALAS2-2023-2320 advisory.

- MiniZip in zlib through 1.3 has an integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip4_64 via a long filename, comment, or extra field. NOTE: MiniZip is not a supported part of the zlib product. (CVE-2023-45853)
