+Subject: [PATCH] cairo: Fix CVE-2017-9814
+
+The bug happens because in some scenarios the variable size can
+have a value of 0 at line 1288. And malloc(0) is not returning
+NULL as some people could expect:
+
+ https://stackoverflow.com/questions/1073157/zero-size-malloc
+
+malloc(0) returns the smallest chunk possible. So the line 1290
+with the return is not execute. And the execution continues with
+an invalid map.
+
+Since the size is 0 the variable map is not initialized correctly
+at load_trutype_table. So, later when the variable map is accessed
+previous values from a freed chunk are used. This could allows an
+attacker to control the variable map.
+
+This patch have not merge in upstream now.
+
+Upstream-Status: Backport [https://bugs.freedesktop.org/show_bug.cgi?id=101547]
