Upgrade fluent-plugin-s3 to version 1.8.5 or higher.
Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the in_s3 process. An attacker can cause excessive memory consumption by uploading a highly compressed file that decompresses to a large size, leading to resource exhaustion and potential disruption of service.
Workaround
This vulnerability can be mitigated by applying strict IAM access controls to limit write (PUT) access to the monitored S3 bucket to only trusted services and administrators, preventing untrusted uploads.
