Summary

Buffer overflow and format vulnerabilities in functions exposed without unsafe

Details

ncurses exposes functions from the ncurses library which:

Pass buffers without length to C functions that may write an arbitrary amount of data, leading to a buffer overflow. (instr, mvwinstr, etc)
Passes rust &str to strings expecting C format arguments, allowing hostile input to execute a format string attack, which trivially allows writing arbitrary data to stack memory (functions in the printw family).

Vulnerability from github – Published: 2021-08-25 20:58 – Updated: 2023-06-13 18:30

Summary

Mishandling of format strings in ncurses

Details

ncurses exposes functions from the ncurses library which: * Pass buffers without length to C functions that may write an arbitrary amount of data, leading to a buffer overflow. (instr, mvwinstr, etc) * Passes rust &str to strings expecting C format arguments, allowing hostile input to execute a format string attack, which trivially allows writing arbitrary data to stack memory (functions in the printw family).

Severity

7.5 (High)

Detection rules are retrieved from Rulezet.

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.
