Affected Packages State

Platform Package State
Red Hat Enterprise Linux 5 vim Out of support scope
Unless explicitly stated as not affected, all previous versions of packages in any minor update stream of a product listed here should be assumed vulnerable, although may not have been subject to full analysis.

Mitigation

The vulnerability can be triggered only if `modeline` is enabled. You can check whether `modeline` is enabled within vim via the command `:set modeline?`
It can be turned off explicitly by adding `set nomodeline` in a vimrc file.
