"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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."

"According to its self-reported version number, the Oracle Primavera Unifier installation running on the remote web
server is 16.1.x or 16.2.x prior to 16.2.15.10, or 17.7.x through 17.12.x prior to 17.12.11.1, or 18.8.x prior to
18.8.13.0. It is, therefore, affected by multiple vulnerabilities:

    - An unspecified flaw exists in how 'default typing' is handled when 'ehcache' is used in the
      jackson-databind component of Primavera Unifier. An unauthenticated, remote attacker can exploit this
      via the network over HTTP to cause remote code execution. (CVE-2019-14379)

    - An information disclosure vulnerability exists in the jackson-databind component of Primavera Unifier.
      An unauthenticated, remote attacker can exploit this via an externally exposed JSON endpoint if the
      service has the mysql-connector-java jar in the classpath, and the attacker can host a crafted MySQL
      server accessible by the victim. An attacker can send a crafted JSON message to read arbitrary local
      files on the server. (CVE-2019-12086)

    - An information disclosure vulnerability exists in the jackson-databind component of Primavera Unifier.
      An unauthenticated, remote attacker can exploit this via an externally exposed JSON endpoint if the
      service has the logback jar in the classpath, which can allow information disclosure. (CVE-2019-14439)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
