+    magicolor: Added security mediation to device discovery
+
+    Extraction of values from the SNMP response were not checked.
+    Also fixed a bug that mistakenly matched any SNMP OIDs with the
+    first model in the model list, in function mc_get_device_from_identification().

+
+    magicolor: Added security remediation for pixels_per_line.
+
+    This implements a security issue reported by GitHub Security Lab.
+    The details are disclosed in GitLab issue #279.
+    The issue relates to an invalid scan parameter block being sent to
+    the backend containing 8 bytes of 0x00 which leads to pixels_per_line
+    being set to 0. Later arithmetic involves the division by this value
+    which causes a div by zero crash.
