RUSTSEC-2019-0006: Buffer overflow and format vulnerabilities in functions exposed without unsafe

[github-actions]

Buffer overflow and format vulnerabilities in functions exposed without unsafe

Details
Package	ncurses
Version	5.99.0
URL	rustsec/advisory-db#106
Date	2019-06-15

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).

See advisory page for additional details.
