A memory allocation flaw was found in the way the MP2T dissector of Wireshark, a network traffic analyzer, processed capture files containig invalid pointer values used for packet length specification. A remote attacker could provide a specially-crafted packet capture file (causing unsigned length value to be reduced by more than its value, resulting into it being a very large value and attempt to allocate large amount of memory when reassembling the packet tvbuff to the requested length), which once opened by a local unsuspecting user would lead to wireshark executable abort.
