                   Red Hat Security Advisory

Synopsis:          Important: rh-eclipse47-jackson-databind security update
Advisory ID:       RHSA-2017:3189-01
Product:           Red Hat Developer Tools
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:3189
Issue date:        2017-11-13
CVE Names:         CVE-2017-15095 
=====================================================================

1. Summary:

An update for rh-eclipse47-jackson-databind is now available for Red Hat
Developer Tools.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Developer Tools for Red Hat Enterprise Linux Server (v. 7) - noarch
Red Hat Developer Tools for Red Hat Enterprise Linux Workstation (v. 7) - noarch

3. Description:

The jackson-databind package provides general data-binding functionality
for Jackson, which works on top of Jackson core streaming API.

Security Fix(es):

* A deserialization flaw was discovered in the jackson-databind which could
allow an unauthenticated user to perform code execution by sending the
maliciously crafted input to the readValue method of the ObjectMapper. This
issue extends the previous flaw CVE-2017-7525 by blacklisting more classes
that could be used maliciously. (CVE-2017-15095)

Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting this issue.

4. Solution:
