The wget packages provide the GNU Wget file retrieval utility for HTTP, HTTPS, and FTP protocols.

Security Fix(es):

  • It was found that wget used a file name provided by the server for the downloaded file when following an HTTP redirect to a FTP server resource. 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-2016-4971)

Red Hat would like to thank GNU wget project for reporting this issue. Upstream acknowledges Dawid Golunski as the original reporter.

Additional Changes:
