  "details" : [ "Vim is an open source, command line text editor. Prior to version 9.2.0074, a heap-based buffer overflow out-of-bounds read exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file, Vim can be tricked into reading up to 7 bytes beyond the allocated memory boundary. Version 9.2.0074 fixes the issue.", "A flaw was found in Vim. When processing a specially crafted Emacs-style tags file, a heap-based buffer overflow out-of-bounds read vulnerability allows an attacker to trick Vim into reading up to 7 bytes beyond its allocated memory boundary. This could lead to information disclosure or potentially affect the integrity of the application." ],
