The ICMPv6 parser in tcpdump before 4.9.3 has a buffer over-read in print-icmp6.c. El analizador ICMPv6 en tcpdump versiones anteriores a 4.9.3, presenta una lectura excesiva del búfer en el archivo print-icmp6.c. An out-of-bounds read vulnerability was discovered in tcpdump while printing ICMP6 packets captured in a pcap file or coming from the network. A remote attacker may abuse this flaw by sending specially crafted packets that, when printed, would trigger the flaw and crash the application. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00053.html http://seclists.org/fulldisclosure/2019/Dec/26 https://github.com/the-tcpdump-group/tcpdump/blob/tcpdump-4.9/CHANGES https://github.com/the-tcpdump-group/tcpdump/commit/d7505276842e85bfd067fa21cdb32b8a2dc3c5e4 https://lists.debian.org/debian-lts-announce/2019/10/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/ • CWE-125: Out-of-bounds Read •
