RHBA-2012:1353 - Bug Fix Advisory

Topic

Updated wget packages that fix one bug are now available for Red Hat Enterprise
Linux 6.

Description

The wget packages provide 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.

This update fixes the following bugs:

• Prior to this update, the wget package contained a redundant URL to the wget

upstream project. This update modifies the specification file to list the
correct http://www.gnu.org/software/wget/. (BZ#754168)

• Prior to this update, the wget utility did not previously work as intended

with the "-T, --timeout" option set when http server did not answer the SSL
handshake. Wget source code has been patched, to ensure that wget aborts the
connection when using --timeout option correctly. (BZ#814208)

• Prior to this update, the wget utility source code was lacking check of the

HTTP response parsing function return value. In some cases, when HTTP response
header was malformed (fuzzed), the parsing function returned error. Because the
returned value was not checked, it then resulted in Segmentation Fault. This
update adds check of the HTTP response parsing function return value in the wget
source code. Now when HTTP response header is malformed (fuzzed) and the parsing
function returns error, the following error message is thrown and wget retries
the request. (BZ#714893)
"2012-10-01 10:13:44 ERROR -1: Malformed status line."

All users of wget are advised to upgrade to these updated packages, which fix
this bug.
