As proposed in #240 and tracked in #414, this PR translates all advisories into the new "V3" advisory format, which is based on Markdown with leading TOML front matter. This format makes it easier to see rendered Markdown syntax descriptions, whether rendered by an IDE or GitHub. This should help with both crafting advisories initially as well as review, and ideally encourages more lengthy descriptions. Support for this format shipped in `cargo-audit` v0.12.0 on May 6th, 2020.

# Buffer overflow and format vulnerabilities in functions exposed without unsafe
|
|
|
|
`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).
