From ${URL} : cairo-truetype-subset.c in cairo 1.15.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) because of mishandling of an unexpected malloc(0) call. Upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=101547 @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.
