HIGH Summary
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a Netscaler file parser infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by changing the restrictions on file size.

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.
