------------------------------------------------------------------

Holy cow, [~Lerh Low]. Thanks for all the background info. Based on that, it 
looks like it is not imperative to upgrade the previous versions of casandra, 
and thus upgrading trunk is sufficient.

+1 on the patch for trunk, and committed as sha 
{{76ef78b7d74972bd235159ca304648ab439fb715}}. Thanks!

> The Jackson being used by Cassandra is really old (1.9.2, and still 
> references codehaus (Jackson 1) instead of fasterxml (Jackson 2)). 
> There have been a few jackson vulnerabilities recently (mostly around 
> deserialization which allows arbitrary code execution)
> [https://nvd.nist.gov/vuln/detail/CVE-2017-7525]
>  [https://nvd.nist.gov/vuln/detail/CVE-2017-15095]
>  [https://nvd.nist.gov/vuln/detail/CVE-2018-1327]
>  [https://nvd.nist.gov/vuln/detail/CVE-2018-7489]
> Given that Jackson in Cassandra is really old and seems to be used also for 
> reading in values, it looks worthwhile to update Jackson to 2.9.5.
