Created mingw-cairo tracking bugs for this issue: Affects: epel-7 [bug 1318978] Upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=89521 Reproducer is available there. Note last update in comment #2: > However, the original author of that patch (ilia.softway) has > expressed doubts that this change fully fixes the problem and he is now using > an additional patch to cell_list_add_subspan() in cairo-tor_scan-converter.c. > > Therefore, I think it is best to leave this bug open until the root cause is > fully understood. 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 |
