Vulnerability from github – Published: 2021-08-25 20:58 – Updated: 2023-06-13 20:01

Summary

Buffer overflow and format vulnerabilities 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

9.8 (Critical)
