medium Nessus Plugin ID 168533

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5768-1 advisory.

 Jan Engelhardt, Tavis Ormandy, and others discovered that the GNU C Library iconv feature incorrectly handled certain input sequences. An attacker could possibly use this issue to cause the GNU C Library to hang or crash, resulting in a denial of service.

 (CVE-2016-10228, CVE-2019-25013, CVE-2020-27618)

 It was discovered that the GNU C Library did not properly handled DNS responses when ENDS0 is enabled. An attacker could possibly use this issue to cause fragmentation-based attacks. (CVE-2017-12132)

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 packages.
