Wireshark is a network traffic analyzer for Unix-ish operating systems. Security Fix(es): In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the SIGCOMP dissector could crash. This was addressed in epan/dissectors/packet-sigcomp.c by correcting the extraction of the length value.(CVE-2018-7418) In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DCERPC SPOOLSS dissector could crash. This was addressed in epan/dissectors/packet-dcerpc-spoolss.c by adding a boundary check.(CVE-2019-10903) In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the GSS-API dissector could crash. This was addressed in epan/dissectors/packet-gssapi.c by ensuring that a valid dissector is called.(CVE-2019-10894) In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the LDSS dissector could crash. This was addressed in epan/dissectors/packet-ldss.c by handling file digests properly.(CVE-2019-10901) In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the NetScaler file parser could crash. This was addressed in wiretap/netscaler.c by improving data validation.(CVE-2019-10895) In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the SRVLOC dissector could crash. This was addressed in epan/dissectors/packet-srvloc.c by preventing a heap-based buffer under-read.(CVE-2019-10899) In Wireshark 2.4.0 to 2.4.3 and 2.2.0 to 2.2.11, the JSON, XML, NTP, XMPP, and GDB dissectors could crash. This was addressed in epan/tvbparse.c by limiting the recursion depth.(CVE-2018-5336) In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, dissectors that support zlib decompression could crash. This was addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid a buffer over-read.(CVE-2018-14340) In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the Bazaar protocol dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-bzr.c by properly handling items that are too long.(CVE-2018-14368) In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the DICOM dissector could go into a large or infinite loop. This was addressed in epan/dissectors/packet-dcm.c by preventing an offset overflow.(CVE-2018-14341) In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the Radiotap dissector could crash. This was addressed in epan/dissectors/packet-ieee80211-radiotap-iter.c by validating iterator operations.(CVE-2018-16057) In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the MMSE dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-mmse.c by preventing length overflows.(CVE-2018-19622) In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the LDSS dissector could crash. This was addressed in epan/dissectors/packet-ldss.c by avoiding a buffer over-read upon encountering a missing '\0' character.(CVE-2018-11362)
