CVE-2022-2264Public exploit

Editor crash via mispositioned put end mark

Published Jul 1, 2022 · Updated Aug 3, 2024

Heap-based buffer overflow in Vim before 9.0 allows attackers to crash the editor by inducing a user to open a crafted file. In do_put() in src/register.c, unused indentation spaces remain in totlen, so an exclusive Visual-mode put places the operation's end mark beyond the line and inc() reads past the allocated buffer. Exploitation requires user interaction with a crafted file and interrupts only the Vim process; published downstream analysis reports no data impact.
