Descriptions

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.

An arbitrary code execution vulnerability was found in LuaTeX (TeX Live) that allows any document compiled with older versions of LuaTeX to execute arbitrary shell commands, even with shell escape disabled.

Max Chernoff discovered that improperly secured shell-escape in LuaTeX may result in arbitrary shell command execution, even with shell escape disabled, if specially crafted tex files are processed.
