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: 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)
