Detail

Problem 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.

2. Relevant releases/architectures:

Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

Title: DSA-1904-1 wget -- insufficient input validation
Description: Daniel Stenberg discovered that wget, a network utility to retrieve files from the Web using http and ftp, is vulnerable to the "Null Prefix Attacks Against SSL/TLS Certificates" published at the Blackhat conference some time ago. This allows an attacker to perform undetected man-in-the-middle attacks via a crafted ITU-T X.509 certificate with an injected null byte in the Common Name field. For the oldstable distribution, this problem has been fixed in version 1.10.2-2+etch1. For the stable distribution, this problem has been fixed in version 1.11.4-2+lenny1. For the testing distribution, this problem will be fixed soon. For the unstable distribution, this problem has been fixed in version 1.12-1. We recommend that you upgrade your wget packages.
