The dissect_attribute_value_pairs function in packet-radius.c for Ethereal 0.8.13 to 0.10.2 allows remote attackers to cause a denial of service (crash) via a malformed RADIUS packet that triggers a null dereference.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
