Vim heap-use-after-free in src/arglist.c:207

The UNIX editor Vim prior to version 9.1.0678 has a use-after-free error in argument list handling. When adding a new file to the argument list, this triggers `Buf*` autocommands. If in such an autocommand the buffer that was just opened is closed (including the window where it is shown), this causes the window structure to be freed which contains a reference to the argument list that we are actually modifying. Once the autocommands are completed, the references to the window and argument list are no longer valid and as such cause an use-after-free. Impact is low since the user must either intentionally add some unusual autocommands that wipe a buffer during creation (either manually or by sourcing a malicious plugin), but it will crash Vim. The issue has been fixed as of Vim patch v9.1.0678.

释放后使用

Vim 安全漏洞

Vim是Vim开源的一款跨平台的文本编辑器。 Vim 9.1.0678之前版本存在安全漏洞，该漏洞源于在参数列表处理中存在释放后重用错误，导致释放包含对我们实际正在修改的参数列表的引用的窗口结构。
