Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue.

Summary
  • (es) Vim es un editor de texto de código abierto y de línea de comandos. Antes de la versión 9.2.0075, hay un desbordamiento negativo de búfer basado en el montón en la lógica de análisis de archivos de etiquetas estilo Emacs de Vim. Al procesar un archivo de etiquetas malformado donde un delimitador aparece al inicio de una línea, Vim intenta leer memoria inmediatamente anterior al búfer asignado. La versión 9.2.0075 corrige el problema.
