CVE-2020-15945

Name of the Vulnerable Software and Affected Versions Lua versions prior to 5.4.1

Description The issue is related to a segmentation fault in the changedline function in ldebug.c, which can be triggered when luaG traceexec is called. This occurs because the code incorrectly assumes that the oldpc value is always updated when the flow of control returns to a function.

Recommendations For Lua versions prior to 5.4.1, update to version 5.4.1 or later to resolve the issue.
