Description Laura Pardo 2018-05-23 15:28:37 UTC
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 Q.931 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/dissectors/packet-q931.c by avoiding a use-after-free after a malformed packet prevented certain cleanup.
