RHEL 3 / 4 / 5 : wget (RHSA-2009:1549)

medium Nessus Plugin ID 42359

Synopsis

The remote Red Hat host is missing a security update.

Description

An updated wget package that fixes a security issue is now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

GNU Wget is a file retrieval utility that can use HTTP, HTTPS, and FTP.

Daniel Stenberg reported that Wget is affected by the previously published 'null prefix attack', caused by incorrect handling of NULL characters in X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse Wget into accepting it by mistake. (CVE-2009-3490)

Wget users should upgrade to this updated package, which contains a backported patch to correct this issue.

Solution

Update the affected wget package.
