Ubuntu 16.04 LTS / 18.04 LTS : Vim vulnerabilities (USN-4582-1)

medium Nessus Plugin ID 183639

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4582-1 advisory.

 It was discovered that Vim incorrectly handled permissions on the .swp file. A local attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 16.04 LTS.
 (CVE-2017-17087)

 It was discovered that Vim incorrectly handled restricted mode. A local attacker could possibly use this issue to bypass restricted mode and execute arbitrary commands. Note: This update only makes executing shell commands more difficult. Restricted mode should not be considered a complete security measure.
 (CVE-2019-20807)

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.
