Description SMASH SMASH 2023-10-30 08:53:49 UTC

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.

Comment 10 Martin Schreiner 2024-06-19 20:02:16 UTC

I don't think this bug is relevant anymore, as the following codestreams are all shipping Vim 9.1.0330 as of today:

SLE-12:Update
SLE-15-SP5:Update
SLE-15:Update

This CVE is also mentioned on its changelog, so the reference is not missing anywhere.
I'm closing it.

Comment 11 Martin Schreiner 2024-06-20 13:20:30 UTC

Reassigning to security.
