+Backport commits ed19bc806809ad10c4ddce515d375581b86ede85 and
+aaf794439e40a2ef544f15b50c20e657414dec7a to address CVE-2019-13290.

+Commit ed19bc806809ad10c4ddce515d375581b86ede85:
+> Bug 701118: Handle appending large display list nodes.
+> 
+> The size of the begin layer node depends on the size of the layer
+> name. That name may be a string from the page's property resources,
+> and is only bounded by memory when parsed by lex_string(). So the
+> append_list_node() logic cannot simply double the size of the
+> display list and hope that the node fits, since the node may be
+> of arbitrary size.
+> 
+> Now append_list_node() would repeatedly double the size of the
+> display list until the node fits, or malloc() runs out of memory.
+
+Commit aaf794439e40a2ef544f15b50c20e657414dec7a:
+> Bug 701118: Limit size of begin layer nodes in display list.
+> 
+> The size of the begin layer node depends on the size of the layer
+> name. That name may be a string from the page's property resources,
+> and is only bounded by memory when parsed by lex_string(). The
+> layer name may cause a display node to be larger than the maximum
+> size allowed. This condition is now checked for.
