CVSS: 7.5EPSS: 0%CPEs: 83EXPL: 0CVE-2018-14880 – tcpdump: Buffer over-read in ospf6_print_lshdr() function in print-ospf6.c
https://notcve.org/view.php?id=CVE-2018-14880
The OSPFv3 parser in tcpdump before 4.9.3 has a buffer over-read in print-ospf6.c:ospf6_print_lshdr(). El analizador OSPFv3 en tcpdump versiones anteriores a 4.9.3, presenta una lectura excesiva del búfer en la función print-ospf6.c:ospf6_print_lshdr(). An out-of-bounds read vulnerability was discovered in tcpdump while printing OSPFv3 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/e01c9bf76740802025c9328901b55ee4a0c49ed6 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: 97%CPEs: 96EXPL: 0CVE-2019-11479 – kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service
https://notcve.org/view.php?id=CVE-2019-11479
Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363. Jonathan Looney descubrió que el tamaño máximo de segmento (MSS) por defecto del kernel de Linux está codificado a 48 bytes. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2020-010.txt http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/108818 https://access.redhat.com/errata/RHSA-2019:1594 https://access.redhat.com/errata/RHSA-2019:1602 https://access.redhat.com/errata/RHSA-2019:1699 https://access.redhat.com/security/vulnerabili • CWE-400: Uncontrolled Resource Consumption CWE-405: Asymmetric Resource Consumption (Amplification) CWE-770: Allocation of Resources Without Limits or Throttling •
