jackson-databind (2.4.2-2+deb8u4) jessie-security; urgency=high
* Team upload.
* Fix CVE-2018-7489: allows unauthenticated remote code execution because of
an incomplete fix for the CVE-2017-7525 deserialization flaw. This is
exploitable by sending maliciously crafted JSON input to the readValue
method of the ObjectMapper, bypassing a blacklist that is ineffective if
the c3p0 libraries are available in the classpath. (Closes: #891614)

jackson-databind (2.4.2-2+deb8u3) jessie-security; urgency=high
* Team upload.
* Fix CVE-2017-17485 and CVE-2018-5968:
Bybass of deserialization blackist to disallow unauthenticated remote code
execution. These CVE exist due to an incomplete fix for CVE-2017-7525.
