Description Laura Pardo 2018-05-23 11:20:01 EDT

A flaw was found in Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the LTP dissector and other dissectors could consume excessive memory. It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. This was addressed in epan/tvbuff.c by rejecting negative lengths.
