Amazon Linux 2 : zlib (ALAS-2023-2320)

critical Nessus Plugin ID 184287

Language:

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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update zlib' to update your system.
