ID: | 202003-04 |
Synopsis
A vulnerability has been found in Vim and gVim concerning how certain modeline options are treated.Background
Vim is an efficient, highly configurable improved version of the classic ‘vi’ text editor. gVim is the GUI version of Vim.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
app-editors/gvim | < 8.1.1486 | >= 8.1.1486 | All supported architectures |
app-editors/vim | < 8.1.1486 | >= 8.1.1486 | All supported architectures |
Description
It was found that the
:source!command was not restricted by the sandbox mode. If modeline was explicitly enabled, opening a specially crafted text file in vim could result in arbitrary command execution.
Impact
A remote attacker could entice a user to open a specially crafted file using Vim or gVim, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
All Vim users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-editors/vim-8.1.1486"
All gVim users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/gvim-8.1.1486"
