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 •

The command-line argument parser in tcpdump before 4.9.3 has a buffer overflow in tcpdump.c:get_next_file(). El analizador de argumentos de la línea de comandos en tcpdump versiones anteriores a 4.9.3, presenta un desbordamiento de búfer en tcpdump.c:get_next_file(). An out-of-bounds write vulnerability was discovered in tcpdump while reading the file passed to the -V option of the command line program. An attacker may abuse this flaw by tricking a victim user into using a malicious file with the -V option, which would make the program read one byte before a stack-based allocated buffer and potentially write a NULL byte to it. • 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/9ba91381954ad325ea4fd26b9c65a8bd9a2a85b6 https://lists.debian.org/debian-lts-announce/2019/10/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
