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.
