Name of the Vulnerable Software and Affected Versions Vim versions prior to 9.2.0075

Description Vim, an open source command line text editor, contains a heap-based buffer underflow issue in its Emacs-style tags file parsing logic. When processing a malformed tags file containing a delimiter at the start of a line, Vim attempts to read memory before the allocated buffer. This can potentially lead to a denial-of-service condition.

Recommendations Versions prior to 9.2.0075 should be updated to version 9.2.0075 or later.
