Package : jackson-databind
Version : 2.4.2-2+deb8u5
CVE ID : CVE-2018-11307 CVE-2018-12022 CVE-2018-12023 CVE-2018-14718
CVE-2018-14719 CVE-2018-14720 CVE-2018-14721 CVE-2018-19360
CVE-2018-19361 CVE-2018-19362
Several deserialization flaws were discovered in jackson-databind, a fast
and powerful JSON library for Java, which could allow an unauthenticated
user to perform code execution. The issue was resolved by extending
the blacklist and blocking more classes from polymorphic deserialization.
For Debian 8 "Jessie", these problems have been fixed in version
2.4.2-2+deb8u5.
We recommend that you upgrade your jackson-databind packages.
