Debian DLA-888-1 : logback security update

critical Nessus Plugin ID 99252

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
