So it's more of a stopgap "fix" than anything complete. |
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.
