CVEs (cve.mitre.org):	CVE-2009-3490

Details

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

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
