Description Huzaifa S. Sidhpurwala 2013-05-22 11:33:08 UTC

A denial of service flaw was found in the way ASN.1 BER dissector of Wireshark, a network traffic analyzer, processed certain ASN.1 BER packet capture files. Remote attacker could provide a specially-crafted ASN.1 BER packet capture file that, when processed would lead to tshark executable crash.
