AIX 7.2 TL 4 : tcpdump (IJ20786)

critical Nessus Plugin ID 132733
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote AIX host is missing a security patch.

Description

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-14467 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-14467 The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_MP). The VRRP parser in tcpdump before 4.9.3 has a buffer over-read in print-vrrp.c:vrrp_print(). The LMP parser in tcpdump before 4.9.3 has a buffer over-read in print-lmp.c:lmp_print_data_link_subobjs(). The Babel parser in tcpdump before 4.9.3 has a buffer over-read in print-babel.c:babel_print_v2(). tcpdump before 4.9.3 mishandles the printing of SMB data (issue 2 of 2). The LDP parser in tcpdump before 4.9.3 has a buffer over-read in print-ldp.c:ldp_tlv_print(). tcpdump before 4.9.3 mishandles the printing of SMB data (issue 1 of 2).
Tcpdump is vulnerable to a buffer overflow, caused by improper bounds checking by the lmp_print_data_link_subobjs function in print-lmp.c.
By sending specially-crafted data, a remote attacker could overflow a buffer and cause the application to crash. The Rx parser in tcpdump before 4.9.3 has a buffer over-read in print-rx.c:rx_cache_find() and rx_cache_insert(). The IKEv1 parser in tcpdump before 4.9.3 has a buffer over-read in print-isakmp.c:ikev1_n_print(). The FRF.16 parser in tcpdump before 4.9.3 has a buffer over-read in print-fr.c:mfr_print(). The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_RESTART). The ICMP parser in tcpdump before 4.9.3 has a buffer over-read in print-icmp.c:icmp_print(). The OSPFv3 parser in tcpdump before 4.9.3 has a buffer over-read in print-ospf6.c:ospf6_print_lshdr(). The RSVP parser in tcpdump before 4.9.3 has a buffer over-read in print-rsvp.c:rsvp_obj_print(). The SMB parser in tcpdump before 4.9.3 has buffer over-reads in print-smb.c:print_trans() for \MAILSLOT\BROWSE and \PIPE\LANMAN. The SMB parser in tcpdump before 4.9.3 has stack exhaustion in smbutil.c:smb_fdata() via recursion. The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_attr_print() (MP_REACH_NLRI). lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks. The command-line argument parser in tcpdump before 4.9.3 has a buffer overflow in tcpdump.c:get_next_file(). The HNCP parser in tcpdump before 4.9.3 has a buffer over-read in print-hncp.c:print_prefix(). The DCCP parser in tcpdump before 4.9.3 has a buffer over-read in print-dccp.c:dccp_print_option(). The IEEE 802.11 parser in tcpdump before 4.9.3 has a buffer over-read in print-802_11.c for the Mesh Flags subfield. The BGP parser in tcpdump before 4.9.3 allows stack consumption in print-bgp.c:bgp_attr_print() because of unlimited recursion. The ICMPv6 parser in tcpdump before 4.9.3 has a buffer over-read in print-icmp6.c. tcpdump before 4.9.3 has a heap-based buffer over-read related to aoe_print in print-aoe.c and lookup_emem in addrtoname.c.
