Package : jackson-databind
Version : 2.4.2-2+deb8u6
CVE ID : CVE-2019-12086
Debian Bug : 929177
A Polymorphic Typing issue was discovered in jackson-databind, a JSON
library for Java. When Default Typing is enabled (either globally or
for a specific property) for an externally exposed JSON endpoint, the
service has the mysql-connector-java jar (8.0.14 or earlier) in the
classpath, and an attacker can host a crafted MySQL server reachable
by the victim, an attacker can send a crafted JSON message that allows
them to read arbitrary local files on the server. This occurs because of
missing com.mysql.cj.jdbc.admin.MiniAdmin validation.
For Debian 8 "Jessie", this problem has been fixed in version
2.4.2-2+deb8u6.
We recommend that you upgrade your jackson-databind packages.
