Bug#961298: jodd: CVE-2018-21234: Potential vulnerability in JSON deserialization

[Salvatore Bonaccorso]

Source: jodd
Version: 3.8.6-1
Severity: grave
Tags: security upstream
Justification: user security hole
Forwarded: https://github.com/oblac/jodd/issues/628

Hi,

The following vulnerability was published for jodd. I'm filling it as
RC severity since altough one might dispute the severity for the issue
itself, it looks that in Debian there was ever only one upload of
jodd, there are no reverse (build) dependencies neither.

Is the package acutally of some use or planned use?

CVE-2018-21234[0]:
| Jodd before 5.0.4 performs Deserialization of Untrusted JSON Data when
| setClassMetadataName is set.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
