Red Hat: RHSA-2016:2587 Moderate: Wget File Upload Threat

red hat
Calendar Grey November 3, 2016
Scroller Redhat
Ubuntu has released a crucial patch for curl addressing session hijacking vulnerabilities and software errors. Implement the patch without delay!
An update for wget is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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.
