Name of the Vulnerable Software and Affected Versions
Lua versions 5.1 through 5.2.x before 5.2.3
Description
The issue is caused by a buffer overflow in the vararg functions in ldo.c, allowing context-dependent attackers to cause a denial of service (crash) via a small number of arguments to a function with a large number of fixed arguments. This can be exploited by a remote attacker using a large number of variable-length arguments.
Recommendations
For Lua versions 5.1 through 5.2.x before 5.2.3, update to version 5.2.3 or later to resolve the issue.
As a temporary workaround, consider restricting the number of arguments passed to functions with a large number of fixed arguments to minimize the risk of exploitation.
