An update is available for tcpdump.
This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
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: 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)
