Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 944850.
In Mitre's CVE dictionary: CVE-2019-18848.

More information:

The json-jwt gem before 1.11.0 for Ruby lacks an element count during the splitting of a JWE string.

Therefore, there was a need to explicitly specify the number of elements when splitting a JWE string.

For Debian 9 stretch, this problem has been fixed in version 1.6.2-1+deb9u2.

We recommend that you upgrade your ruby-json-jwt packages.
