The host is installed Wireshark 1.2.0 through 1.2.14 or 1.4.0 through 1.4.3 and is prone to a heap-based buffer overflow vulnerability. A flaw is present in the application, which fails to properly handle a long record in a Nokia DCT3 trace file. Successful exploitation allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact.
