Description Huzaifa S. Sidhpurwala 2012-01-20 06:47:18 UTC

A heap-based buffer underflow issue was found in way wireshark parsed LANalyzer packet capture files. It may be possible to make Wireshark crash or possibly execute arbitrary code (with the persmisisons of the user running wireshark) by convincing someone to read a malformed
IPTrace packet capture file.  This is corrected in upstream 1.4.11 and 1.6.5.
