Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : ncurses vulnerability (USN-6684-1)

medium Nessus Plugin ID 191736

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6684-1 advisory.

 It was discovered that ncurses incorrectly handled certain function return values, possibly leading to segmentation fault. A local attacker could possibly use this to cause a denial of service (system crash).

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

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

Solution

Update the affected packages.
