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.\n\n## Affected\n\n- `vim < 9.0.2068`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `vim 9.0.2068`","depth":"sunlit","depthScore":22,"depthScoreParts":{"impact":22,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
