RHSA-2018:0342: Important: rh-maven35-jackson-databind security update
First published: Thu Feb 22 2018(Updated: )
The jackson-databind package provides general data-binding functionality for Jackson, which works on top of Jackson core streaming API.<br>Security Fix(es):<br><li> 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. (CVE-2017-7525)</li> <li> Further classes that an attacker could use to achieve code execution through deserialisation were discovered, and added to the blacklist introduced by CVE-2017-7525. (CVE-2017-15095, CVE-2017-17485)</li> Red Hat would like to thank Liao Xinxi (NSFOCUS) for reporting CVE-2017-7525 and CVE-2017-15095 and 0c0c0f from 360观星实验室 for reporting CVE-2017-17485.
