Description of problem ---------------------- clean fails to build if "-Werror=format-security" flag is used. ... cgawas.c:1040:2: error: format not a string literal and no format arguments [-Werror=format-security] cgawas.c:198:2: error: format not a string literal and no format arguments [-Werror=format-security] cgawas.c:3836:4: error: format not a string literal and no format arguments [-Werror=format-security] cgawas.c:3851:4: error: format not a string literal and no format arguments [-Werror=format-security] ... We are working on a proposal to enable "-Werror=format-security" for all packages. Once this flag is enabled, GCC will refuse to compile code that could be vulnerable to a string format security flaw. For more details, please see https://fedorahosted.org/fesco/ticket/1185 page. To understand why it is important to fix this, please see https://fedoraproject.org/wiki/Format-Security-FAQ page. How to fix this --------------- The fix for these errors is quite simple. It's a matter of changing a line like, printf(foo); to read, printf("%s", foo); That's it. Please fix this issue in rawhide with a patch (which you should submit to upstream to merge moving forward). Please do a new build with the fix in rawhide. Other releases do not need to be directly fixed, but there should be no harm in pushing out this fix/patch with other needed changes to those branches. In the event you don't fix this bug before the next mass rebuild, provenpackagers may step in and update your package(s) to fix this issue. How reproducible ---------------- Build clean-2.4-16.fc21.src.rpm with "-Werror=format-security" flag to reproduce the problem. To make this process easier, you can use a modified "redhat-rpm-config" package from http://people.fedoraproject.org/~halfie/artifacts/redhat-rpm-config/ URL. $ sha256sum redhat-rpm-config-9.1.0-56.fc20.* faad7594b2080fe76497d0ce50808c905a93dd7b41c1defdde5ca57e3833d3d2 redhat-rpm-config-9.1.0-56.fc20.noarch.rpm 5aa9357174305c7285ffdbc92d7ffe1c07a8a95d5459b930461308f5aad75413 redhat-rpm-config-9.1.0-56.fc20.src.rpm
I am currently working on fixing this, but it takes a while because this is a very complex program.

I have looked into this issue, and decided against fixing this. The problem here is that upstream is not releasing any new versions for the current compiler anytime soon, as they're rewriting it basically from scratch. While the fix is easy per-line, given the amount of lines that Werror=format-security complains about, this is just undoable to maintain a patch for. I have reported this upstream and send them a patch, but I have no idea if they will merge it, and if they do whether a new release will come out anytime. Unfortunately, this means I have had to orphan the Clean package in Fedora for now.
