RHBA-2012:1353 - wget bug fix update

Synopsis

wget bug fix update

Type/Severity

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.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
