<< Back VID 50098 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description The version of Wireshark installed on the remote Windows host is 1.12.x prior to 1.12.13. It is, therefore, affected by multiple denial of service vulnerabilities : - A NULL pointer dereference flaw exists in the dissect_nds_request() function in packet-ncp2222.inc due to improper handling of packets. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an application crash. (CVE-2016-6504) - A denial of service vulnerability exists due to a divide-by-zero flaw in the dissect_pbb_tlvblock() function in packet-packetbb.c. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an application crash. (CVE-2016-6505) - A flaw exists in the add_headers() function in packet_wsp.c that is triggered when an offset of zero is returned by the wkh_content_disposition() function. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an infinite loop, resulting in a denial of service condition. (CVE-2016-6506) - A flaw exists in the tvb_get_guintvar() function in packet-mmse.c that is triggered during the handling of an overly large length value. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an infinite loop, resulting in a denial of service condition. (CVE-2016-6507) - A denial of service vulnerability exists due to an incorrect integer data type used in the rlc_decode_li() function in packet-rlc.c. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause a long loop and excessive CPU resource consumption, resulting in a denial of service condition. (CVE-2016-6508) - A denial of service vulnerability exists in the dissect_ldss_transfer() function in packet-ldss.c that is triggered when recreating a conversation that already exists. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause an application crash. (CVE-2016-6509) - An overflow condition exists in the rlc_decode_li() function in packet-rlc.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause a stack-based buffer overflow, resulting in a denial of service condition. (CVE-2016-6510) - A denial of service vulnerability exists in the proto_tree_add_text_valist_internal() function in proto.c due to improper handling of packets. An unauthenticated, remote attacker can exploit this, via a specially crafted packet or packet trace file, to cause a long loop and excessive CPU resource consumption. (CVE-2016-6511) * Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts. * References: https://www.wireshark.org/security/wnpa-sec-2016-40.html https://www.wireshark.org/security/wnpa-sec-2016-41.html https://www.wireshark.org/security/wnpa-sec-2016-42.html https://www.wireshark.org/security/wnpa-sec-2016-43.html https://www.wireshark.org/security/wnpa-sec-2016-44.html https://www.wireshark.org/security/wnpa-sec-2016-45.html https://www.wireshark.org/security/wnpa-sec-2016-46.html https://www.wireshark.org/security/wnpa-sec-2016-47.html https://www.wireshark.org/docs/relnotes/wireshark-1.12.13.html * Platforms Affected: Wireshark versions 1.12.x prior to 1.12.13 Microsoft Windows Any version Recommendation Upgrade to the latest version Wireshark (1.12.13 or later), available from the Wireshark.org Web site at http://www.wireshark.org/download/win32/all-versions/ Related URL CVE-2016-6504,CVE-2016-6505,CVE-2016-6506,CVE-2016-6507,CVE-2016-6508,CVE-2016-6509,CVE-2016-6510,CVE-2016-6511 (CVE) Related URL 92163,92164,92165,92166,92167,92168,92169,92173 (SecurityFocus) Related URL (ISS)
