DescriptionCVE.org

Tanium addressed a compression bomb vulnerability in Findings.

AnalysisAI

Compression bomb processing in Tanium Findings exposes authenticated network attackers to a limited availability impact by submitting specially crafted, highly compressed data that causes disproportionate resource consumption upon decompression. The CVSS score of 3.1 (Low) reflects the constrained impact - availability degradation rather than complete service loss - and the requirement for authenticated access with high attack complexity. …
