Technical Summary
This advisory covers four distinct vulnerabilities in Vim on Red Hat Enterprise Linux 8.8: CVE-2026-25749 allows arbitrary code execution through the 'helpfile' option processing; CVE-2026-28417 enables arbitrary code execution via OS command injection in the netrw plugin; CVE-2026-28421 permits denial of service and information disclosure through crafted swap files; and CVE-2026-33412 allows arbitrary code execution via command injection in the glob() function.
