Several security issues were fixed in Vim.

Releases

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 14.04 ESM. (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. This issue only affected Ubuntu 14.04 ESM.
(CVE-2019-20807)
