Details

Out-of-bounds Read vulnerability in dail8859 NotepadNext (src/lua/src modules). This vulnerability is associated with program files lparser.C.

This issue affects NotepadNext: through v0.11.

The singlevar() in lparser.c lacks a certain luaK_exp2anyregup call, leading to a heap-based buffer over-read that might affect a system that compiles untrusted Lua code.
