It was found that perl can load modules from the current directory if not found in the module directories, via the @INC path. A local, authenticated attacker could create a specially crafted module in a writable directory and trick a user into running a perl program from that directory, if the module is not found in previous @INC paths, it will load and execute the attacker's module.(CVE-2016-1238)");
