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.

The version of Wireshark installed on the remote Windows host is 2.0.x prior to 2.0.10 or 2.2.x prior to 2.2.4. It is, therefore, affected by multiple denial of service vulnerabilities :

  - A denial of service vulnerability exists when handling     DHCPv6 packets due to an integer overflow condition in     file epan/dissectors/packet-dhcpv6.c. An     unauthenticated, remote attacker can exploit this to     cause the program to enter a large loop that consumes     excessive CPU resources (CVE-2017-5597).

  - A denial of service vulnerability exists in the     asterix_fspec_len() function within file     epan/dissectors/packet-asterix.c due to an infinite loop     flaw that is triggered because certain input is     improperly validated. An unauthenticated, remote     attacker can exploit this to consume excessive CPU     resources (CVE-2017-5596).

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In Wireshark 2.2.0 to 2.2.3 and 2.0.0 to 2.0.9, the DHCPv6 dissector could go into a large loop, triggered     by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-dhcpv6.c by     changing a data type to avoid an integer overflow. (CVE-2017-5597)

Note that Nessus relies on the presence of the package as reported by the vendor.

Wireshark was updated to version 2.2.6, which brings several new features, enhancements and bug fixes. Thses security issues were fixed :

  - CVE-2017-7700: In Wireshark the NetScaler file parser     could go into an infinite loop, triggered by a malformed     capture file. This was addressed in wiretap/netscaler.c     by ensuring a nonzero record size (bsc#1033936)

  - CVE-2017-7701: In Wireshark the BGP dissector could go     into an infinite loop, triggered by packet injection or     a malformed capture file. This was addressed in     epan/dissectors/packet-bgp.c by using a different     integer data type (bsc#1033937)

  - CVE-2017-7702: In Wireshark the WBXML dissector could go     into an infinite loop, triggered by packet injection or     a malformed capture file. This was addressed in     epan/dissectors/packet-wbxml.c by adding length     validation (bsc#1033938)

  - CVE-2017-7703: In Wireshark the IMAP dissector could     crash, triggered by packet injection or a malformed     capture file. This was addressed in     epan/dissectors/packet-imap.c by calculating a line's     end correctly (bsc#1033939)

  - CVE-2017-7704: In Wireshark the DOF dissector could go     into an infinite loop, triggered by packet injection or     a malformed capture file. This was addressed in     epan/dissectors/packet-dof.c by using a different     integer data type and adjusting a return value     (bsc#1033940)

  - CVE-2017-7705: In Wireshark the RPC over RDMA dissector     could go into an infinite loop, triggered by packet     injection or a malformed capture file. This was     addressed in epan/dissectors/packet-rpcrdma.c by     correctly checking for going beyond the maximum offset     (bsc#1033941)

  - CVE-2017-7745: In Wireshark the SIGCOMP dissector could     go into an infinite loop, triggered by packet injection     or a malformed capture file. This was addressed in     epan/dissectors/packet-sigcomp.c by correcting a     memory-size check (bsc#1033942)

  - CVE-2017-7746: In Wireshark the SLSK dissector could go     into an infinite loop, triggered by packet injection or     a malformed capture file. This was addressed in     epan/dissectors/packet-slsk.c by adding checks for the     remaining length (bsc#1033943)

  - CVE-2017-7748: In Wireshark the WSP dissector could go     into an infinite loop, triggered by packet injection or     a malformed capture file. This was addressed in     epan/dissectors/packet-wsp.c by adding a length check     (bsc#1033945)

  - CVE-2017-6014: In Wireshark a crafted or malformed     STANAG 4607 capture file will cause an infinite loop and     memory exhaustion. If the packet size field in a packet     header is null, the offset to read from will not     advance, causing continuous attempts to read the same     zero length packet. This will quickly exhaust all system     memory (bsc#1025913)

  - CVE-2017-5596: In Wireshark the ASTERIX dissector could     go into an infinite loop, triggered by packet injection     or a malformed capture file. This was addressed in     epan/dissectors/packet-asterix.c by changing a data type     to avoid an integer overflow (bsc#1021739)

  - CVE-2016-9375: In Wireshark the DTN dissector could go     into an infinite loop, triggered by network traffic or a     capture file. This was addressed in     epan/dissectors/packet-dtn.c by checking whether SDNV     evaluation was successful (bsc#1010740)

  - CVE-2016-9374: In Wireshark the AllJoyn dissector could     crash with a buffer over-read, triggered by network     traffic or a capture file. This was addressed in     epan/dissectors/packet-alljoyn.c by ensuring that a     length variable properly tracked the state of a     signature variable (bsc#1010752)

  - CVE-2016-9373: In Wireshark the DCERPC dissector could     crash with a use-after-free, triggered by network     traffic or a capture file. This was addressed in     epan/dissectors/packet-dcerpc-nt.c and     epan/dissectors/packet-dcerpc-spoolss.c by using the     wmem file scope for private strings (bsc#1010754)

  - CVE-2016-7180: epan/dissectors/packet-ipmi-trace.c in     the IPMI trace dissector in Wireshark did not properly     consider whether a string is constant, which allowed     remote attackers to cause a denial of service     (use-after-free and application crash) via a crafted     packet (bsc#998800)

  - CVE-2016-7179: Stack-based buffer overflow in     epan/dissectors/packet-catapult-dct2000.c in the     Catapult DCT2000 dissector in Wireshark allowed remote     attackers to cause a denial of service (application     crash) via a crafted packet (bsc#998963)

  - CVE-2016-7178: epan/dissectors/packet-umts_fp.c in the     UMTS FP dissector in Wireshark did not ensure that     memory is allocated for certain data structures, which     allowed remote attackers to cause a denial of service     (invalid write access and application crash) via a     crafted packet (bsc#998964)

  - CVE-2016-7177: epan/dissectors/packet-catapult-dct2000.c     in the Catapult DCT2000 dissector in Wireshark did not     restrict the number of channels, which allowed remote     attackers to cause a denial of service (buffer over-read     and application crash) via a crafted packet (bsc#998763)

  - CVE-2016-7176: epan/dissectors/packet-h225.c in the     H.225 dissector in Wireshark called snprintf with one of     its input buffers as the output buffer, which allowed     remote attackers to cause a denial of service (copy     overlap and application crash) via a crafted packet     (bsc#998762)

  - CVE-2016-7175: epan/dissectors/packet-qnet6.c in the     QNX6 QNET dissector in Wireshark mishandled MAC address     data, which allowed remote attackers to cause a denial     of service (out-of-bounds read and application crash)     via a crafted packet (bsc#998761)

  - CVE-2016-6354: Heap-based buffer overflow in the     yy_get_next_buffer function in Flex might have allowed     context-dependent attackers to cause a denial of service     or possibly execute arbitrary code via vectors involving     num_to_read (bsc#990856).
