Vim is an improved version of the good old UNIX editor Vi. Heap-use-after-free in memory allocated in the function ga_grow_inner in in the file src/alloc.c at line 748, which is freed in the file src/ex_docmd.c in the function do_cmdline at line 1010 and then used again in src/cmdhist.c at line 759. When using the :history command, it’s possible that the provided argument overflows the accepted value. Causing an Integer Overflow and potentially later an use-after-free. This vulnerability has been patched in version 9.0.2068.
