Subject: [PATCH] patch 9.1.2148: [security]: Buffer overflow in netbeans
|
||||
interface
|
||||
|
||||
Problem: [security]: Buffer overflow in netbeans special_keys() handling
|
||||
Solution: Limit writing to max KEYBUFLEN bytes to prevent writing out of
|
||||
bounds.

Upstream-Status: Backport [https://github.com/vim/vim/commit/c5f312aad8e4179e437f81ad39a860cd0ef11970]
|
||||
|
||||
Backport Changes:
|
||||
- Excluded changes to src/version.c from this backport. This file only tracks
|
||||
upstream version increments. We are applying a security fix, not a version
|
||||
upgrade. These changes were skipped to maintain current package versioning
|
||||
and avoid merge conflicts.
