| Package | Affected versions | Patched versions |
|---|---|---|
| luatex | ≥ 1.04, < 1.16.2 | 1.16.2 |
| miktex | ≥ 2.9.6300, < 23.5 | 23.5 |
| tex live | ≥ 2017, < 2023 | 2023 |
LuaTeX before 1.17.0 allows execution of arbitrary shell commands when compiling a TeX file obtained from an untrusted source. This occurs because luatex-core.lua lets the original io.popen be accessed. This also affects TeX Live before 2023 r66984 and MiKTeX before 23.5.
