An update of the redis package has been released.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2019:2002 advisory.

  - A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before     3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By carefully corrupting a hyperloglog using the SETRANGE     command, an attacker could trick Redis interpretation of dense HLL encoding to write up to 3 bytes beyond     the end of a heap-allocated buffer. (CVE-2019-10192)

  - A stack-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x     before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By corrupting a hyperloglog using the SETRANGE     command, an attacker could cause Redis to perform controlled increments of up to 12 bytes past the end of     a stack-allocated buffer. (CVE-2019-10193)

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

From Red Hat Security Advisory 2019:2002 :

An update for the redis:5 module is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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: Heap buffer overflow in HyperLogLog triggered by malicious client (CVE-2019-10192)

* redis: Stack buffer overflow in HyperLogLog triggered by malicious client (CVE-2019-10193)

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.

It was discovered that Redis incorrectly handled the hyperloglog data structure. An attacker could use this issue to cause Redis to crash, resulting in a denial of service, or possibly execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201908-04 (Redis: Multiple vulnerabilities)
