CVE-2015-4590 is a medium-severity flaw (CVSS 5.0) affecting arduino json. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The extractFrom function in Internals/QuotedString.cpp in Arduino JSON before 4.5 allows remote attackers to cause a denial of service (crash) via a JSON string with a \ (backslash) followed by a terminator, as demonstrated by "\\\0", which triggers a buffer overflow and over-read.
Why this priority
- Public exploit reference
A fixed release or distro patch exists.
