Ubuntu Security Notice USN-3464-1
October 26, 2017

wget vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- - Ubuntu 17.10
- - Ubuntu 17.04
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Wget.

Software Description:
- - wget: retrieves files from the web

Details:

Antti Levomäki, Christian Jalio, and Joonas Pihlaja discovered that Wget
incorrectly handled certain HTTP responses. A remote attacker could use
this issue to cause Wget to crash, resulting in a denial of service, or
possibly execute arbitrary code. (CVE-2017-13089, CVE-2017-13090)

Dawid Golunski discovered that Wget incorrectly handled recursive or
mirroring mode. A remote attacker could possibly use this issue to bypass
intended access list restrictions. (CVE-2016-7098)

Orange Tsai discovered that Wget incorrectly handled CRLF sequences in
HTTP headers. A remote attacker could possibly use this issue to inject
arbitrary HTTP headers. (CVE-2017-6508)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.10:
  wget                            1.19.1-3ubuntu1.1

Ubuntu 17.04:
  wget                            1.18-2ubuntu1.1

Ubuntu 16.04 LTS:
  wget                            1.17.1-1ubuntu1.3

Ubuntu 14.04 LTS:
  wget                            1.15-1ubuntu1.14.04.3

In general, a standard system update will make all the necessary changes.
