- - -----------------------------------------------------------------------
Package : ruby-json-jwt
Version : 1.6.2-1+deb9u2
CVE ID : CVE-2019-18848
Debian Bug : 944850
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.
For the detailed security status of ruby-json-jwt please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/ruby-json-jwt
