It is recommended that administrators running jackson-databind check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- 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.
