===================================================================== Red Hat Security Advisory
Synopsis: Moderate: wget security and bug fix update Advisory ID: RHSA-2016:2587-02 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2587.html Issue date: 2016-11-03 CVE Names: CVE-2016-4971 =====================================================================
1. Summary:
An update for wget is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64
3. Description:
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.
