"Several minor issues have been fixed in vim, a highly configurable
text editor.

CVE-2017-11109

Vim allows attackers to cause a denial of service (invalid free) or
possibly have unspecified other impact via a crafted source (aka -S)
file.

CVE-2017-17087

Vim sets the group ownership of a .swp file to the editor's primary
group (which may be different from the group ownership of the original
file), which allows local users to obtain sensitive information by
leveraging an applicable group membership.

CVE-2019-12735

Vim did not restrict the `:source!` command when executed in a
sandbox.

For Debian 8 'Jessie', these problems have been fixed in version
2:7.4.488-7+deb8u4.

We recommend that you upgrade your vim packages.
