DescriptionGitHub Advisory

Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf) with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command. The issue has been fixed as of Vim patch v9.1.2148.

AnalysisAI

Stack buffer overflow in Vim's NetBeans integration allows a malicious NetBeans server to corrupt memory and potentially crash the editor or execute arbitrary code through a specially crafted specialKeys command. The vulnerability affects Vim builds with NetBeans support enabled and requires user interaction to connect to a compromised server. A patch is available in Vim version 9.1.2148 and later.
