DescriptionGitHub Advisory

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.

AnalysisAI

Vim versions prior to 9.2.0074 contain a heap buffer overflow in the Emacs-style tags file parser that allows reading up to 7 bytes of out-of-bounds memory when processing malformed tags files. A local attacker can trigger this vulnerability through a crafted tags file to leak sensitive information from the application's memory. The vulnerability has been patched in version 9.2.0074 and later.

Technical ContextAI
