RedHat: RHSA-2017-3189:01 Important: rh-eclipse47-jackson-databind security
Summary
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.
