Overview
Affected versions of this package are vulnerable to Out-of-bounds Write via the pf_cluster_stats function. An attacker can execute arbitrary code or cause a denial of service by sending a crafted geometry_msgs/PoseWithCovarianceStamped message with extreme covariance values to the /initialpose topic, resulting in a negative index write into heap memory preceding the allocated buffer.
Note: This is only exploitable if the application is running in Release mode, as the boundary check is compiled out in this configuration.
