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.

    descriptionThe 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.
