Amazon Linux AMI : zlib (ALAS-2022-1650)

critical Nessus Plugin ID 168601

Language:

Synopsis

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

Description

The version of zlib installed on the remote host is prior to 1.2.8-7.20. It is, therefore, affected by a vulnerability as referenced in the ALAS-2022-1650 advisory.

 - 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)

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.
