K44551633 : Multiple tcpdump vulnerabilities

Security Advisory Description

• CVE-2018-10103

tcpdump before 4.9.3 mishandles the printing of SMB data (issue 1 of 2).

• CVE-2018-10105

tcpdump before 4.9.3 mishandles the printing of SMB data (issue 2 of 2).

• CVE-2018-14882

The ICMPv6 parser in tcpdump before 4.9.3 has a buffer over-read in print-icmp6.c.

• CVE-2019-15166

lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks.

• CVE-2018-16230

The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_attr_print() (MP_REACH_NLRI).

• CVE-2018-16300

The BGP parser in tcpdump before 4.9.3 allows stack consumption in print-bgp.c:bgp_attr_print() because of unlimited recursion.

• CVE-2018-14881

The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_RESTART).

• CVE-2018-16229

The DCCP parser in tcpdump before 4.9.3 has a buffer over-read in print-dccp.c:dccp_print_option().

• CVE-2018-16228

The HNCP parser in tcpdump before 4.9.3 has a buffer over-read in print-hncp.c:print_prefix().

• CVE-2018-16227

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.

• CVE-2018-16451

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.

• CVE-2018-16452

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.
