Summary
eth-abi is vulnerable to recursive DoS
Details
This is related to recent ZST stuff (https://github.com/ethereum/eth-abi/security/advisories/GHSA-rqr8-pxh7-cq3g), but it's a different one. Basically a recursive pointer issue

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
