libwiretap8: In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the LBMPDM dissector could crash
CVE-2018-19623 is fixed in 10 products on 1 platform, first by libwireshark-data 2.6.5-1~ubuntu18.04.0, released November 28, 2018. It is not reported as exploited. Patch Radar priority: Routine.
In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the LBMPDM dissector could crash. In addition, a remote attacker could write arbitrary data to any memory locations before the packet-scoped memory. This was addressed in epan/dissectors/packet-lbmpdm.c by disallowing certain negative values.
