Vim is an open source, command line text editor. Prior to version 9.2.0496, a code injection vulnerability exists in s:stepmatch() in the cucumber filetype plugin (runtime/ftplugin/cucumber.vim) on Vim builds with +ruby support. Step-definition patterns read from .rb files under the repository's features/*/ or stories/*/ directories are embedded into a Ruby Kernel.eval argument without sufficient escaping, allowing a crafted pattern in an attacker-controlled repository to execute arbitrary Ruby (and through it arbitrary shell commands) when the user invokes a step-jump mapping ([d, ]d). This issue has been patched in version 9.2.0496.

Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex compiler, when encountering a collection containing a combining character as the endpoint of a character range (e.g. [0-0\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states. This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind assertion, it dereferences state->out1->out without a NULL check, causing a segmentation fault. This vulnerability is fixed in 9.2.0137.

Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue.

Vim is an open source, command line text editor. Versions prior to 9.2.0077 have a heap-buffer-overflow and a segmentation fault (SEGV) exist in Vim's swap file recovery logic. Both are caused by unvalidated fields read from crafted pointer blocks within a swap file. Version 9.2.0077 fixes the issue.

Vim is an open source command line text editor. Vim < v9.1.0647 has double free in src/alloc.c:616. When closing a window, the corresponding tagstack data will be cleared and freed. However a bit later, the quickfix list belonging to that window will also be cleared and if that quickfix list points to the same tagstack data, Vim will try to free it again, resulting in a double-free/use-after-free access exception. Impact is low since the user must intentionally execute vim with several non-default flags, but it may cause a crash of Vim. The issue has been fixed as of Vim patch v9.1.0647

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.

The Netrw plugin (netrw.vim) in Vim 7.0 and 7.1 allows user-assisted attackers to execute arbitrary commands via shell metacharacters in a filename used by the (1) "D" (delete) command or (2) b:netrw_curdir variable, as demonstrated using the netrw.v4 and netrw.v5 test cases.

Vim is an open source, command line text editor. Prior to 9.2.0663, a Vimscript code injection vulnerability exists in s:NetrwLocalRmFile() in the netrw plugin (runtime/pack/dist/opt/netrw/autoload/netrw.vim) when deleting a local file from the browser. A filename derived from the buffer's directory listing is interpolated into an Ex command line passed to :execute with only the backslash character escaped, allowing a crafted filename containing a bar (|) to terminate the intended command and execute arbitrary Vimscript, including shell commands via :call system() and :!. This vulnerability is fixed in 9.2.0663.

Vim is an open source, command line text editor. Prior to 9.2.0479, a command injection vulnerability exists in tar#Vimuntar() in runtime/autoload/tar.vim when decompressing .tgz archives on Unix-like systems. The function builds :!gunzip and :!gzip -d commands using shellescape(tartail) without the {special} flag, allowing a crafted archive filename to trigger Vim cmdline-special expansion and execute shell commands in the user's context. This vulnerability is fixed in 9.2.0479.

Vim is an open source, command line text editor. Prior to version 9.2.0383, an OS command injection vulnerability exists in the netrw standard plugin bundled with Vim. By inducing a user to open a crafted URL (e.g., using the sftp:// or file:// protocol handlers), an attacker can execute arbitrary shell commands with the privileges of the Vim process. This issue has been patched in version 9.2.0383.

Vim is an open source, command line text editor. Prior to 9.2.0357, A command injection vulnerability exists in Vim's tag file processing. When resolving a tag, the filename field from the tags file is passed through wildcard expansion to resolve environment variables and wildcards. If the filename field contains backtick syntax (e.g., `command`), Vim executes the embedded command via the system shell with the full privileges of the running user.

Vim before 9.2.0272 allows code execution that happens immediately upon opening a crafted file in the default configuration, because %{expr} injection occurs with tabpanel lacking P_MLE.

Vim is an open source, command line text editor. Prior to version 9.2.0276, a modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The `complete`, `guitabtooltip` and `printheader` options are missing the `P_MLE` flag, allowing a modeline to be executed. Additionally, the `mapset()` function lacks a `check_secure()` call, allowing it to be abused from sandboxed expressions. Commit 9.2.0276 fixes the issue.

Vim is an open source, command line text editor. Prior to version 9.2.0202, a command injection vulnerability exists in Vim's glob() function on Unix-like systems. By including a newline character (\n) in a pattern passed to glob(), an attacker may be able to execute arbitrary shell commands. This vulnerability depends on the user's 'shell' setting. This issue has been patched in version 9.2.0202.

Vim is an open source, command line text editor. Prior to version 9.2.0073, an OS command injection vulnerability exists in the `netrw` standard plugin bundled with Vim. By inducing a user to open a crafted URL (e.g., using the `scp://` protocol handler), an attacker can execute arbitrary shell commands with the privileges of the Vim process. Version 9.2.0073 fixes the issue.

The Netrw plugin 125 in netrw.vim in Vim 7.2a.10 allows user-assisted attackers to execute arbitrary code via shell metacharacters in filenames used by the execute and system functions within the (1) mz and (2) mc commands, as demonstrated by the netrw.v2 and netrw.v3 test cases. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2008-2712.

The shellescape function in Vim 7.0 through 7.2, including 7.2a.10, allows user-assisted attackers to execute arbitrary code via the "!" (exclamation point) shell metacharacter in (1) the filename of a tar archive and possibly (2) the filename of the first file in a tar archive, which is not properly handled by the VIM TAR plugin (tar.vim) v.10 through v.22, as demonstrated by the shellescape, tarplugin.v2, tarplugin, and tarplugin.updated test cases. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2008-2712. NOTE: this issue has the same root cause as CVE-2008-3075. NOTE: due to the complexity of the associated disclosures and the incomplete information related to them, there may be inaccuracies in this CVE description and in external mappings to this identifier.

In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands via scripting interfaces (e.g., Python, Ruby, or Lua).
