CVSS: 7.5EPSS: 0%CPEs: 12EXPL: 0CVE-2018-14461 – tcpdump: Buffer over-read in ldp_tlv_print() function in print-ldp.c
https://notcve.org/view.php?id=CVE-2018-14461
The LDP parser in tcpdump before 4.9.3 has a buffer over-read in print-ldp.c:ldp_tlv_print(). El analizador LDP en tcpdump versiones anteriores a 4.9.3, presenta una lectura excesiva del búfer en print-ldp.c:ldp_tlv_print(). An out-of-bounds read vulnerability was discovered in tcpdump while printing LDP 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/aa5c6b710dfd8020d2c908d6b3bd41f1da719b3b 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 •
CVSS: 7.5EPSS: 2%CPEs: 1EXPL: 0CVE-2018-16300 – tcpdump: Resource exhaustion in bgp_attr_print() function in print-bgp.c
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 •

The command-line argument parser in tcpdump before 4.99.0 has a buffer overflow in tcpdump.c:read_infile(). To trigger this vulnerability the attacker needs to create a 4GB file on the local filesystem and to specify the file name as the value of the -F command-line argument of tcpdump. El analizador de argumentos de la línea de comandos en tcpdump antes de la versión 4.99.0 tiene un desbordamiento de búfer en tcpdump.c:read_infile(). Para desencadenar esta vulnerabilidad, el atacante necesita crear un archivo de 4GB en el sistema de archivos local y especificar el nombre del archivo como valor del argumento de línea de comandos -F de tcpdump • https://github.com/the-tcpdump-group/tcpdump/commit/ad7c25bc0decf96dc7768c9e903734d38528b1bd • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
