From ${URL} : Hello, ## Overview I and my colleague have found a vulnerability of Cairo-1.15.4 when fuzzing HarfBuzz with AFL. Cairo is a 2d graphics library, and HarBuzz is an OpenType text shaping engine which contains a tool named *hb-view* to give a graphical view of text using Cairo with a font provided by user. Owing to logical problem in program, the crash happens during null pointer deference and the vulnerability will cause a denial-of-service attack with a crafted font file. ## Note I have reported this issue to cairo and here is the link: https://bugs.freedesktop.org/show_bug.cgi?id=100763. When I disclosure to Red Hat Product Security, they suggest me to use CVE-2017-7475 for this issue and I have communicated this number to upstream. @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

Maintainers, please take a look at this. RedHat decided that they are not going to fix this. https://access.redhat.com/security/cve/cve-2017-7475

This remains open with no patch: https://gitlab.freedesktop.org/cairo/cairo/issues/80
(In reply to Sam James (sec padawan) from comment #4) > This remains open with no patch: > https://gitlab.freedesktop.org/cairo/cairo/issues/80 There is a proposed patch (https://bugs.freedesktop.org/attachment.cgi?id=131213) but upstream aren't sure about it: https://gitlab.freedesktop.org/cairo/cairo/issues/80#note_51228. So it's more of a stopgap "fix" than anything complete.
