Debian Security Advisory

DLA-888-1 logback -- LTS security update

Date Reported:
07 Apr 2017
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 857343.
In Mitre's CVE dictionary: CVE-2017-5929.
More information:

It was discovered that logback, a flexible logging library for Java, would deserialize data from untrusted sockets which may lead to the execution of arbitrary code. This issue has been resolved by adding a whitelist to use only trusted classes.

For Debian 7 Wheezy, these problems have been fixed in version 1:1.0.4-1+deb7u1.

We recommend that you upgrade your logback packages.
