Vulnerability from github – Published: 2024-12-02 21:34 – Updated: 2024-12-02 21:34

Summary

`ruzstd` uninit and out-of-bounds memory reads

Details

Affected versions of ruzstd miscalculate the length of the allocated and init section of its internal RingBuffer, leading to uninitialized or out-of-bounds reads in copy_bytes_overshooting of up to 15 bytes.

This may result in up to 15 bytes of memory contents being written into the decoded data when decompressing a crafted archive. This may occur multiple times per archive.

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.
