Stack overflow when parsing specially crafted JSON ABI strings

Affected versions of the alloy-json-abi crate did not properly handle parsing of malformatted JSON ABI strings. The JsonAbi::parse method can be tricked into a stack overflow when processing specially crafted input.

This stack overflow can lead to a crash of the application using this crate, potentially causing a denial of service.

The flaw was corrected in commit 4790c47.
