Vim

Vim is an open source, command line text editor. Prior to version 9.2.0450, a heap buffer overflow exists in read_compound() in src/spellfile.c when loading a crafted spell file (.spl) with UTF-8 encoding active. An attacker-controlled length field in the spell file's compound section overflows a 32-bit signed integer multiplication, causing a small buffer to be allocated for a write loop that runs many iterations, overflowing the heap. Because the 'spelllang' option can be set from a modeline, a text file modeline can trigger spell file loading if a malicious .spl file has been planted on the runtimepath. This issue has been patched in version 9.2.0450.Show less

Vim is an open source, command line text editor. Prior to version 9.2.0435, an OS command injection vulnerability exists in Vim's :find command-line completion. When the path option contains backtick-enclosed shell commands, those commands are executed during file name completion. Because the path option lacks the P_SECURE flag, it can be set from a modeline, allowing an attacker who controls the contents of a file to execute arbitrary shell commands when the user opens that file in Vim and triggers :find completion. This issue has been patched in version 9.2.0435.Show less

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.Show less

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.Show less

Vim is an open source, command line text editor. Prior to 9.2.0316, a command injection vulnerability in Vim's netbeans interface allows a malicious netbeans server to execute arbitrary Ex commands when Vim connects to it, via unsanitized strings in the defineAnnoType and specialKeys protocol messages. This vulnerability is fixed in 9.2.0316.Show less

Vim is an open source, command line text editor. Prior to 9.2.0280, a path traversal bypass in Vim's zip.vim plugin allows overwriting of arbitrary files when opening specially crafted zip archives, circumventing the previous fix for CVE-2025-53906. This vulnerability is fixed in 9.2.0280.Show less

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.Show less

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.Show less

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.Show less

Vim is an open source, command line text editor. Prior to version 9.2.0078, a stack-buffer-overflow occurs in `build_stl_str_hl()` when rendering a statusline with a multi-byte fill character on a very wide terminal. Version 9.2.0078 patches the issue.Show less

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.Show less

Vim is an open source, command line text editor. Prior to version 9.2.0076, a heap-based buffer overflow WRITE and an out-of-bounds READ exist in Vim's terminal emulator when processing maximum combining characters from Unicode supplementary planes. Version 9.2.0076 fixes the issue.Show less

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.Show less

Vim is an open source, command line text editor. Prior to version 9.2.0074, a heap-based buffer overflow out-of-bounds read exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file, Vim can be tricked into reading up to 7 bytes beyond the allocated memory boundary. Version 9.2.0074 fixes the issue.Show less

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.Show less

Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf) with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command. The issue has been fixed as of Vim patch v9.1.2148.Show less

Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been patched in version 9.1.2132.Show less

Vim is an open source, command line text editor. Prior to version 9.1.1947, an uncontrolled search path vulnerability on Windows allows Vim to execute malicious executables placed in the current working directory for the current edited file. On Windows, when using cmd.exe as a shell, Vim resolves external commands by searching the current working directory before system paths. When Vim invokes tools such as findstr for :grep, external commands or filters via :!, or compiler/:make commands, it may inadvertently run a malicious executable present in the same directory as the file being edited. The issue affects Vim for Windows prior to version 9.1.1947.Show less

A security flaw has been discovered in vim up to 9.1.1615. Affected by this vulnerability is the function main of the file src/xxd/xxd.c of the component xxd. The manipulation results in buffer overflow. The attack requires a local approach. The exploit has been released to the public and may be exploited. Upgrading to version 9.1.1616 addresses this issue. The patch is identified as eeef7c77436a78cd27047b0f5fa6925d56de3cb0. It is recommended to upgrade the affected component.Show less
