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 macOS or Mac OS X 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. (CVE-2017-6474)
