CVSS 7.5 · High EPSS 0,62%

Kerentanan Improper Handling of Highly Compressed Data (Data Amplification) pada fluentd. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

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.
