freedup.s390x: W: call-to-mktemp /usr/bin/freedup freedup.s390x: W: call-to-mktemp /usr/bin/symharden This executable calls mktemp. As advised by the manpage (mktemp(3)), this function should be avoided. Some implementations are deeply insecure, and there is a race condition between the time of check and time of use (TOCTOU). See http://capec.mitre.org/data/definitions/29.html for details, and contact upstream to have this issue fixed. 2 packages and 0 specfiles checked; 0 errors, 2 warnings.
