USN-4582-1: Vim vulnerabilities

Releases

• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• vim - Vi IMproved - enhanced vi editor

Details

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)
