tmate.x86_64: W: call-to-mktemp /usr/bin/tmate 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. tmate.src: W: no-version-in-last-changelog tmate.x86_64: W: no-version-in-last-changelog The latest changelog entry doesn't contain a version.
