Description

This security bulletin contains information about 1 vulnerability.


1) Heap-based buffer overflow (CVE-ID: CVE-2026-45130)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to heap-based buffer overflow in read_compound() in src/spellfile.c when loading a crafted .spl spell file with UTF-8 encoding active. A remote attacker can trick the victim into opening a text file with a crafted modeline or otherwise cause Vim to load a planted spell file to cause a denial of service.

User interaction is required, and exploitation requires a malicious .spl file to be present on the runtimepath while UTF-8 encoding is active.
