Vim < 9.1.0648 Double-Free

medium Nessus Plugin ID 205386

Language:

Synopsis

A text editor installed on the remote Windows host is affected a double-free vulnerability.

Description

According to its version, the version of Vim installed on the remote Windows host is prior to 9.1.0648. It is, therefore affected by a double free vulnerability. When abandoning a buffer, Vim may ask the user what to do with the modified buffer. If the user wants the changed buffer to be saved, Vim may create a new Untitled file, if the buffer did not have a name yet. However, when setting the buffer name to Unnamed, Vim will falsely free a pointer twice, leading to a double-free and possibly later to a heap-use-after-free, which can lead to a crash.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Vim version 9.1.0648 or later
