Title: Vim缓冲区溢出漏洞（CNVD-2024-40464）

Description:

Vim（Vi IMproved）是一个功能强大的文本编辑器，起源于最初的Unix编辑器Vi，提供多种模式，包括普通模式、插入模式、命令行模式等，允许用户以高效的方式进行文本编辑和处理。

Vim在9.1.0648之前的版本中存在缓冲区溢出漏洞。该漏洞由于Vim在处理未命名的缓冲区并尝试将其名称设置为"Untitled"时，错误地释放了同一个内存指针两次，导致双释放，从而破坏内存管理器的元数据，导致未定义的行为。攻击者可利用该漏洞导致程序崩溃或不稳定，从而执行拒绝服务攻击。

Severity: 低

Vulnerability from cvelistv5

Published

Modified

Severity ?

4.2 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L

CWE

CWE-416 - Use After Free

Summary

Vim is an open source command line text editor. double-free in dialog_changed() in Vim < v9.1.0648. 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. The issue has been fixed as of Vim patch v9.1.0648.
