RUSTSEC-2020-0002: Parsing a specially crafted message can result in a stack overflow

Parsing a specially crafted message can result in a stack overflow

Details
Package	prost
Version	0.5.0
URL	https://github.com/danburkert/prost/issues/267
Date	2020-01-16
Patched versions	>= 0.6.1

Affected versions of this crate contained a bug in which decoding untrusted
input could overflow the stack.

On architectures with stack probes (like x86), this can be used for denial of
service attacks, while on architectures without stack probes (like ARM)
overflowing the stack is unsound and can result in potential memory corruption
(or even RCE).

The flaw was quickly corrected by @danburkert and released in version 0.6.1.

See advisory page for additional details.
