In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a K12 file parser crash, triggered by a malformed capture file. This was addressed in wiretap/k12.c by validating the relationships between lengths and offsets.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - Multiple integer overflows in Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 allow remote attackers     to cause a denial of service (infinite loop) via vectors related to the (1) BACapp and (2) Bluetooth HCI     dissectors, a different vulnerability than CVE-2012-2392. (CVE-2012-3825)

  - The decompress_sigcomp_message function in epan/sigcomp-udvm.c in the SigComp UDVM dissector in Wireshark     1.10.x before 1.10.11 allows remote attackers to cause a denial of service (buffer over-read and     application crash) via a crafted packet. (CVE-2014-8710)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - The dissector-table implementation in epan/packet.c in Wireshark 1.12.x before 1.12.7 mishandles table     searches for empty strings, which allows remote attackers to cause a denial of service (application crash)     via a crafted packet, related to the (1) dissector_get_string_handle and (2)     dissector_get_default_string_handle functions. (CVE-2015-6243)

  - The dissect_zbee_secure function in epan/dissectors/packet-zbee-security.c in the ZigBee dissector in     Wireshark 1.12.x before 1.12.7 improperly relies on length fields contained in packet data, which allows     remote attackers to cause a denial of service (application crash) via a crafted packet. (CVE-2015-6244)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - The srtp_add_address function in epan/dissectors/packet-rtp.c in the RTP dissector in Wireshark 1.10.x     before 1.10.7 does not properly update SRTP conversation data, which allows remote attackers to cause a     denial of service (application crash) via a crafted packet. (CVE-2014-2907)

  - The dissect_frame function in epan/dissectors/packet-frame.c in the frame metadissector in Wireshark     1.10.x before 1.10.8 interprets a negative integer as a length value even though it was intended to     represent an error condition, which allows remote attackers to cause a denial of service (application     crash) via a crafted packet. (CVE-2014-4020)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

It was discovered that wireshark, a network protocol analyzer, contained several vulnerabilities in the dissectors for ASTERIX, DHCPv6, NetScaler, LDSS, IAX2, WSP, K12 and STANAG 4607, that could lead to various crashes, denial-of-service or execution of arbitrary code.

It was discovered that Wireshark, a network protocol analyzer, contained several vulnerabilities in the dissectors for ASTERIX, DHCPv6, LDSS, IAX2, WSP and RTMPT and the NetScaler and K12 file parsers, that could lead to various crashes, denial of service, or execution of arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 1.12.1+g01b65bf-4+deb8u6~deb7u7.

We recommend that you upgrade your wireshark packages.

The version of Wireshark installed on the remote Windows host is 2.0.x prior to 2.0.11 or 2.2.x prior to 2.2.5. It is, therefore, affected by multiple denial of service vulnerabilities :

  - An infinite loop condition exists in the Netscaler file     parser in the nstrace_read_v20() and nstrace_read_v30()     functions within file wiretap/netscaler.c due to     improper validation of certain input. An     unauthenticated, remote attacker can exploit this, via a     specially crafted capture file, to consume excessive     memory resources, resulting in a denial of service     condition. (CVE-2017-6467)

  - An out-of-bounds read error exists within various     functions in file wiretap/netscaler.c when handling     record lengths. An unauthenticated, remote attacker can     exploit this, via a specially crafted capture file, to     crash the Netscaler file parser process. (CVE-2017-6468)

  - A memory allocation issue exists in the     dissect_ldss_transfer() function within file     epan/dissectors/packet-ldss.c due to improper validation     of certain input. An unauthenticated, remote attacker     can exploit this, via packet injection or a specially     crafted capture file, to crash the LDSS dissector     process. (CVE-2017-6469)

  - An infinite loop condition exists in IAX2 in the     iax2_add_ts_fields() function within file     epan/dissectors/packet-iax2.c when processing     timestamps. An unauthenticated, remote attacker can     exploit this, via packet injection or a specially     crafted capture file, to consume excessive CPU     resources, resulting in a denial of service condition.
    (CVE-2017-6470)

  - An infinite loop condition exists in WSP in the     dissect_wsp_common() function within file     epan/dissectors/packet-wsp.c when handling capability     lengths. An unauthenticated, remote attacker can exploit     this, via packet injection or a specially crafted     capture file, to cause a denial of service condition.
    (CVE-2017-6471)

  - An infinite loop condition exists in the RTMPT dissector     in the dissect_rtmpt_common() function within file     epan/dissectors/packet-rtmpt.c due to improper     validation of certain input. An unauthenticated, remote     attacker can exploit this, via packet injection or a     specially crafted capture file, to consume excessive     memory resources, resulting in a denial of service     condition. (CVE-2017-6472)

  - A denial of service vulnerability exists in the     process_packet_data() function within file wiretap/k12.c     due to improper validation of certain input. An     unauthenticated, remote attacker can exploit this, via a     specially crafted capture file, to crash the K12 file     parser process. (CVE-2017-6473)

  - An infinite loop condition exists in the NetScaler file     parser in the nstrace_read_v10(), nstrace_read_v20(),     and nstrace_read_v30() functions within file     wiretap/netscaler.c when handling record sizes. An     unauthenticated, remote attacker can exploit this, via a     specially crafted capture file, to consume excessive     memory resources, resulting in a denial of service     condition.
