The window of affected versions is somewhere after 1.11.2 until the fix was included in 1.14.2. This leaves epel-7/mingw-cairo and rhel-7.1/cairo affected; all other versions are either prior to the vulnerable code's introduction or (rhel-7.2, fedora, epel/cairo) include the fix.
This CVE was previously addressed in Red Hat Enterprise Linux 7 in the rebase to 1.14.2: https://rhn.redhat.com/errata/RHBA-2015-2116.html
