Executive Summary

Threat Score
74/100CAUTION
Reputation
RELIABLE

This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker could cause a denial of service by sending crafted log data that triggers uncontrolled recursion in glibc regex processing. The image has 41 exposed vulnerabilities, but only two high-severity ones, both related to regex recursion. Post-exploit vulnerabilities are low-severity and not a primary concern.
