"An update for rh-eclipse46-jackson-databind is now available for Red
Hat Software Collections.

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.

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 maliciously crafted input to the readValue method of
ObjectMapper. This issue extends upon the previous flaws CVE-2017-7525
and CVE-2017-15095 by blacklisting more classes that could be used
maliciously. (CVE-2017-17485)

Red Hat would like to thank 0c0c0f from 360Guan Xing Shi Yan Shi  for
reporting this issue."
