=====================================================================
1. Summary:
An updated wget package that fixes one security issue and one bug is now
available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having Low
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 6) – i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) – x86_64
Red Hat Enterprise Linux Server (v. 6) – i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) – i386, x86_64
3. Description:
The wget package provides the GNU Wget file retrieval utility for HTTP,
HTTPS, and FTP protocols. Wget provides various useful features, such as
the ability to work in the background while the user is logged out,
recursive retrieval of directories, file name wildcard matching or updating
files in dependency on file timestamp comparison.
It was discovered that wget used a file name provided by the server when
saving a downloaded file. This could cause wget to create a file with a
different name than expected, possibly allowing the server to execute
arbitrary code on the client. (CVE-2010-2252)
Note: With this update, wget always uses the last component of the original
URL as the name for the downloaded file. Previous behavior of using the
server provided name or the last component of the redirected URL when
creating files can be re-enabled by using the ‘–trust-server-names’
command line option, or by setting ‘trust_server_names=on’ in the wget
start-up file.
This update also fixes the following bugs:
* Prior to this update, the wget package did not recognize HTTPS SSL
certificates with alternative names (subjectAltName) specified in the
certificate as valid. As a consequence, running the wget command failed
with a certificate error. This update fixes wget to recognize such
certificates as valid. (BZ#1060113)
All users of wget are advised to upgrade to this updated package, which
contain backported patches to correct these issues.
