CVE-2022-1927Public exploit

Process crash via zero-line cursor buffer over-read

Published May 29, 2022 · Updated Aug 3, 2024

Buffer over-read in Vim before 8.2.5037 allows local users to crash the editor when a specially crafted file is opened. The parse_cmd_address function leaves the cursor on line zero after a 0; range, causing utf_ptr2char to read beyond its buffer. User interaction is required to open the file; the demonstrated outcome is termination of the Vim process.
