Affected packages

• crates.io ncurses: <= 5.101.0 (no fix yet)

Description

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).
