DLA-1879-1 jackson-databind -- LTS security update

Date Reported:

12 Aug 2019

Affected Packages:

jackson-databind

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 933393.
In Mitre's CVE dictionary: CVE-2019-14379, CVE-2019-14439.

More information:

Deserialization flaws were discovered in jackson-databind relating to EHCache and logback/jndi, 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+deb8u8.

We recommend that you upgrade your jackson-databind packages.
