In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-thrift.c had a large loop that was addressed by not proceeding with dissection after encountering an unexpected type.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-dcm.c had an infinite loop that was addressed by checking for integer wraparound.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-wccp.c had a large loop that was addressed by ensuring that a calculated length was monotonically increasing.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-sccp.c had an infinite loop that was addressed by using a correct integer data type.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-rpki-rtr.c had an infinite loop that was addressed by validating a length field.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-lltd.c had an infinite loop that was addressed by using a correct integer data type.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-openflow_v6.c had an infinite loop that was addressed by validating property lengths.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-usb.c had an infinite loop that was addressed by rejecting short frame header lengths.
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-s7comm.c had an infinite loop that was addressed by correcting off-by-one errors.
The netmonrec_comment_destroy function in wiretap/netmon.c in Wireshark through 2.4.4 performs a free operation on an uninitialized memory address, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
