Debian DLA-2741-1 : commons-io - LTS security update

medium Nessus Plugin ID 152662

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2741 advisory.

 Lukas Euler discovered a path traversal vulnerability in commons-io, a Java library for common useful IO related classes. When invoking the method FileNameUtils.normalize with an improper input string, like //../foo, or \\..\foo, the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus limited path traversal), if the calling code would use the result to construct a path value. For Debian 9 stretch, this problem has been fixed in version 2.5-1+deb9u1. We recommend that you upgrade your commons-io packages. For the detailed security status of commons-io please refer to its security tracker page at: https://security- tracker.debian.org/tracker/commons-io Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at:
 https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the commons-io packages.

For Debian 9 stretch, this problem has been fixed in version 2.5-1+deb9u1.
