Description

CentOS Errata and Security Advisory CESA-2014:0151

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.
