SCA: security update for fluentd (GHSA-j9cw-hwqf-85w7)

high Tenable Cloud Security Plugin ID 444003

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS,
 Hadoop and so on. Prior to 1.19.3, Fluentd's in_http and in_forward plugins support gzip-compressed data
 but enforce limits only on compressed payloads through settings such as body_size_limit and
 chunk_size_limit, allowing crafted compressed payloads to decompress in memory to an excessive size and
 cause denial of service through memory exhaustion. This issue is fixed in version 1.19.3. (CVE-2026-44160)

Solution

Update the fluentd library and its related packages to version 1.19.3 or later.
