RHEL 8 : redis:5 (RHSA-2021:3946)

high Nessus Plugin ID 154312

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for redis:5.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:3946 advisory.

Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log.

Security Fix(es):

* redis: Lua scripts can overflow the heap-based Lua stack (CVE-2021-32626)

* redis: Integer overflow issue with Streams (CVE-2021-32627)

* redis: Integer overflow bug in the ziplist data structure (CVE-2021-32628)

* redis: Denial of service via Redis Standard Protocol (RESP) request (CVE-2021-32675)

* redis: Integer overflow issue with intsets (CVE-2021-32687)

* redis: Integer overflow issue with strings (CVE-2021-41099)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
