Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vims 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.

Weakness

The product writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.
