Security Vulnerabilities fixed in tcpdump RHSA-2020:4760

Description

The tcpdump packages contain the tcpdump utility for monitoring network traffic. The tcpdump utility can capture and display the packet headers on a particular network interface or on all interfaces. The following packages have been upgraded to a later upstream version: tcpdump (4.9.3). (BZ#1804063) Security Fix(es): * tcpdump: SMB data printing mishandled (CVE-2018-10103) * tcpdump: SMB data printing mishandled (CVE-2018-10105) * tcpdump: Out of bounds read/write in get_next_file() in tcpdump.c (CVE-2018-14879) * tcpdump: Buffer over-read in ldp_tlv_print() function in print-ldp.c (CVE-2018-14461) * tcpdump: Buffer over-read in icmp_print() function in print-icmp.c (CVE-2018-14462) * tcpdump: Buffer over-read in vrrp_print() function in print-vrrp.c (CVE-2018-14463) * tcpdump: Buffer over-read in lmp_print_data_link_subobjs() function in print-lmp.c (CVE-2018-14464) * tcpdump: Buffer over-read in rsvp_obj_print() function in print-rsvp.c (CVE-2018-14465) * tcpdump: Buffer over-read in print-icmp6.c (CVE-2018-14466) * tcpdump: Buffer over-read in bgp_capabilities_print() in print-bgp.c (CVE-2018-14467) * tcpdump: Buffer over-read in mfr_print() function in print-fr.c (CVE-2018-14468) * tcpdump: Buffer over-read in ikev1_n_print() function in print-isakmp.c (CVE-2018-14469) * tcpdump: Buffer over-read in babel_print_v2() in print-babel.c (CVE-2018-14470) * tcpdump: Buffer over-read in ospf6_print_lshdr() function in print-ospf6.c (CVE-2018-14880) * tcpdump: Buffer over-read in bgp_capabilities_print() function in print-bgp.c (CVE-2018-14881) * tcpdump: Buffer over-read in function rpl_dio_printopt in print-icmp6.c (CVE-2018-14882) * tcpdump: Buffer over-read in print-802_11.c (CVE-2018-16227) * tcpdump: Access to uninitialized buffer in print_prefix() function in print-hncp.c (CVE-2018-16228) * tcpdump: Buffer over-read in dccp_print_option() function in print-dccp.c (CVE-2018-16229) * tcpdump: Buffer over-read in bgp_attr_print() function in print-bgp.c (CVE-2018-16230) * tcpdump: Resource exhaustion in bgp_attr_print() function in print-bgp.c (CVE-2018-16300) * tcpdump: Buffer over-read in print_trans() function in print-smb.c (CVE-2018-16451) * tcpdump: Resource exhaustion in smb_fdata() funtion in smbutil.c (CVE-2018-16452) * tcpdump: Buffer overflow in lmp_print_data_link_subobjs() in print-lmp.c (CVE-2019-15166) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
