| Doc Text: |
A heap-based buffer overflow vulnerability was found in Vim's utf_ptr2char() function of the src/mbyte.c file. This flaw occurs because there is access to invalid memory with put in visual block mode. An attacker can trick a user into opening a specially crafted file, triggering an out-of-bounds read that causes an application to crash, leading to a denial of service.

Created vim tracking bugs for this issue: Affects: fedora-all [bug 2176463] Hi, the reproducer seems to be a vimscript combination - would you mind explaining why the vulnerability is not low, but medium?

Initial triage set it to medium by description. Lowered to low now. |
