Description Laura Pardo 2018-05-23 11:41:15 EDT

A flaw was found in Wireshark 2.6.0, the IEEE 802.11 protocol dissector could crash. 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/crypt/dot11decrypt.c by avoiding a buffer overflow during FTE processing in Dot11DecryptTDLSDeriveKey.
