Synopsis :

An application installed on the remote Windows host is affected by
multiple denial of service vulnerabilities.

Description :

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. (CVE-2017-6474)

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