Package : jackson-databind
Version : 2.4.2-2+deb8u8
CVE ID : CVE-2019-14379 CVE-2019-14439
Debian Bug : 933393

Deserialization flaws were discovered in jackson-databind relating to
EHCache and logback/jndi, which could allow an unauthenticated user to
perform remote code execution. The issue was resolved by extending the
blacklist and blocking more classes from polymorphic deserialization.

For Debian 8 "Jessie", these problems have been fixed in version
2.4.2-2+deb8u8.

We recommend that you upgrade your jackson-databind packages.
