SynopsisThe remote Debian host is missing a security-related update.
DescriptionUser 'Arminius' discovered a vulnerability in Vim, an enhanced version of the standard UNIX editor Vi (Vi IMproved). The 'Common vulnerabilities and exposures project' identifies the following problem :
Editors typically provide a way to embed editor configuration commands (aka modelines) which are executed once a file is opened, while harmful commands are filtered by a sandbox mechanism. It was discovered that the 'source'command (used to include and execute another file) was not filtered, allowing shell command execution with a carefully crafted file opened in Vim.
SolutionUpgrade the vim packages.
For the stable distribution (stretch), this problem has been fixed in version 2:8.0.0197-4+deb9u2.
