Ubuntu 14.04 LTS / 16.04 LTS / 17.04 / 17.10 : wget vulnerabilities (USN-3464-1)

High Nessus Plugin ID 104211

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Antti Levomaki, 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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected wget package.
