RHBA-2014:1408 - Bug Fix Advisory

Topic

Updated wget packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

GNU Wget is a file retrieval utility which can use either the HTTP, HTTPS, or
FTP protocol. 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.

This update fixes the following bugs:

• Prior to this update, Wget was missing support for Server Name Indication

(SNI). As a consequence, Wget was unable to successfully validate certificates
from a server using SNI, even if the certificate was valid. The SNI support has
been ported to the Wget distributed in Red Hat Enterprise Linux 6, and Wget is
now able to successfully validate certificates from any server using SNI,
provided the certificate is valid. (BZ#909604)

• An error in the Wget code prevented Wget from parsing all web links in

retrieved pages correctly. Consequently, some links were not followed and pages
not retrieved when doing recursive retrieving. The source code has been fixed to
parse web links correctly, and all valid links found in the downloaded pages are
now parsed and followed correctly in the aforementioned scenario. (BZ#960137)

• Due to potential resource leaks in the Wget source code, Wget could leak

memory in some situations. With this update, the source code has been patched to
free resources that could potentially leak, thus fixing this bug. (BZ#873216)

Users of wget are advised to upgrade to these updated packages, which fix these
bugs.
