Description
Wireshark 1.2.0 through 1.2.14, 1.4.0 through 1.4.3, and 1.5.0 frees an uninitialized pointer during processing of a .pcap file in the pcap-ng format, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a malformed file.
