A flaw was found in vim. The vulnerability occurs due to reading beyond the end of a line in the utf_head_off function, which can lead to a heap buffer overflow. This flaw allows an attacker to input a specially crafted file, leading to a crash or code execution.

Mitigation

Untrusted vim scripts with -s [scriptin] are not recommended to run.
