Descriptions

fileio.c in Vim prior to 8.0.1263 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, as demonstrated by /etc/shadow owned by root:shadow mode 0640, but /etc/.shadow.swp owned by root:users mode 0640, a different vulnerability than CVE-2017-1000382.

fileio.c en Vim en versiones anteriores a la 8.0.1263 establece la propiedad de grupo de un archivo .swp en el grupo primario del editor (que puede ser diferente de la propiedad de grupo del archivo original), lo que permite a los usuarios locales obtener información sensible aprovechando una membresía de grupo aplicable, tal y como lo demuestra el hecho de que /etc/shadow es propiedad de root:shadow mode 0640, pero /etc/.shadow.swp es propiedad de root:users mode 0640. Esta es una vulnerabilidad diferente a CVE-2017-1000382.
