Debian DSA-4425-1 : wget - security update

critical Nessus Plugin ID 123799
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Kusano Kazuhiko discovered a buffer overflow vulnerability in the handling of Internationalized Resource Identifiers (IRI) in wget, a network utility to retrieve files from the web, which could result in the execution of arbitrary code or denial of service when recursively downloading from an untrusted server.

Solution

Upgrade the wget packages.

For the stable distribution (stretch), this problem has been fixed in version 1.18-5+deb9u3.
