Ubuntu 14.04 LTS / 16.04 LTS : Wget vulnerabilities (USN-3464-1)

high Nessus Plugin ID 104211

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3464-1 advisory.

 Antti Levomki, 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected wget and / or wget-udeb packages.
