F5F5:K44551633K44551633 : Multiple tcpdump vulnerabilities
Security Advisory Description
tcpdump before 4.9.3 mishandles the printing of SMB data (issue 1 of 2).
tcpdump before 4.9.3 mishandles the printing of SMB data (issue 2 of 2).
The ICMPv6 parser in tcpdump before 4.9.3 has a buffer over-read in print-icmp6.c.
lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks.
The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_attr_print() (MP_REACH_NLRI).
The BGP parser in tcpdump before 4.9.3 allows stack consumption in print-bgp.c:bgp_attr_print() because of unlimited recursion.
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 DCCP parser in tcpdump before 4.9.3 has a buffer over-read in print-dccp.c:dccp_print_option().
The HNCP parser in tcpdump before 4.9.3 has a buffer over-read in print-hncp.c:print_prefix().
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 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.
Impact
These vulnerabilities can result in denial of service (DoS) or, potentially, execution of arbitrary code.
