CVSS: 7.5EPSS: 0%CPEs: 12EXPL: 0CVE-2018-16228 – tcpdump: Access to uninitialized buffer in print_prefix() function in print-hncp.c
https://notcve.org/view.php?id=CVE-2018-16228
The HNCP parser in tcpdump before 4.9.3 has a buffer over-read in print-hncp.c:print_prefix(). El analizador HNCP en tcpdump versiones anteriores a 4.9.3, presenta una lectura excesiva del búfer en print-hncp.c:print_prefix(). A flaw was found in tcpdump where an uninitialized buffer is accessed in tcpdump while printing HNCP 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. System availability is the highest threat from this vulnerability. • 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/83a412a5275cac973c5841eca3511c766bed778d 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 CWE-665: Improper Initialization •

https://notcve.org/view.php?id=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. El analizador BGP en tcpdump versiones anteriores a 4.9.3, permite el consumo de pila en print-bgp.c:bgp_attr_print() debido a una recursividad ilimitada. An uncontrolled resource consumption flaw was discovered in the way tcpdump prints BGP packets. The BGP protocol allows ATTR_SET to be nested as many times as the message can accommodate, however when a specially crafted packet is crafted and parsed by tcpdump, this may lead to stack exhaustion due to uncontrolled recursion. System availability is the highest threat from this vulnerability. • 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/af2cf04a9394c1a56227c2289ae8da262828294a https://lists.debian.org/debian-lts-announce/2019/10/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/ • CWE-400: Uncontrolled Resource Consumption CWE-674: Uncontrolled Recursion •
