DLA-2030-1 jackson-databind -- LTS security update

Date Reported:

10 Dec 2019

Affected Packages:

jackson-databind

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2019-17267, CVE-2019-17531.

More information:

More deserialization flaws were discovered in jackson-databind which could allow an unauthenticated user to perform remote 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+deb8u10.

We recommend that you upgrade your jackson-databind packages.
