Descriptions

getchar.c in Vim before 8.1.1365 and Neovim before 0.3.6 allows remote attackers to execute arbitrary OS commands via the :source! command in a modeline, as demonstrated by execute in Vim, and assert_fails or nvim_input in Neovim.

El archivo getchar.c en Vim anterior a versión 8.1.1365 y Neovim anterior a versión 0.3.6 permite a los atacantes remotos ejecutar comandos arbitrarios del sistema operativo por medio de: comando source! en el componente modeline, como es demostrado por la ejecución en Vim, y assert_fails o nvim_input en Neovim.

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.

It was discovered that Vim incorrectly handled certain files. An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 16.04 LTS. It was discovered that Vim incorrectly handled certain files. An attacker could possibly use this issue to execute arbitrary code.
