CVE-2023-48232

Vim 8.0 allows attackers to cause a denial of service (invalid free) or possibly have unspecified other impact via a crafted source (aka -S) file.

Vim before patch 8.0.0056 does not properly validate values for the 'filetype', 'syntax', and 'keymap' options, which may result in the execution of arbitrary code if a file with a specially crafted modeline is opened.

Vim is an improved version of the Unix vi text editor. When flushing the typeahead buffer, Vim moves the current position in the typeahead buffer but does not check whether there is enough space left in the buffer to handle the next characters. This may lead to the tb_off position within the buffer being out of bounds.

In Vim before 9.1.0764, a use-after-free occurs when closing a buffer and a BufWinLeave auto command reopens the same buffer in a new split window.

A vulnerability in Vim before version 9.2.0272 allows immediate code execution upon opening a crafted file in the default configuration. The issue is due to %{expr} injection in tabpanel lacking the P_MLE flag.

An integer overflow at an unserialize_uep memory allocation site occurs for vim before patch 8.0.0378, if it does not properly validate values for tree length when reading a corrupted undo file, which may lead to resultant buffer overflows.

An integer overflow at a u_read_undo memory allocation site would occur for vim before patch 8.0.0377, if it does not properly validate values for tree length when reading a corrupted undo file, which may lead to resultant buffer overflows.

Vim before patch 8.0.0322 does not properly validate values for tree length when handling a spell file, which may result in an integer overflow at a memory allocation site and a resultant buffer overflow.

Vim's netrw plugin contains a vulnerability that allows arbitrary Vimscript execution via a crafted filename with quote characters and expression fragments. This can lead to shell command execution with the privileges of the user running Vim.

Vim prior to 9.2.0845 has a vulnerability in StructMembers() in runtime/autoload/ccomplete.vim, which constructs and executes a vimgrep command using an insufficiently escaped typeref: or typename: value from a tags file, allowing an unterminated collection followed by a command separator to execute arbitrary Ex and operating-system commands when a user invokes C omni-completion with CTRL-X CTRL-O on a member access whose type is resolved from that tags file. This issue is fixed in version 9.2.0845.
