Vim - 'mch_expand_wildcards()' Heap Buffer Overflow
source: https://www.securityfocus.com/bid/30648/info
Vim is prone to a heap-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.
An attacker may exploit this issue to execute arbitrary code with the privileges of the user running the application. Failed exploit attempts will likely result in denial-of-service conditions.
This issue affects Vim 6.2.429 through 6.3.058.
