Description

Incomplete fix for CVE-2021-3101. Hotdog, prior to v1.0.2, did not mimic the resource limits, device restrictions, or syscall filters of the target JVM process. This would allow a container to exhaust the resources of the host, modify devices, or make syscalls that would otherwise be blocked.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity high, availability high.
