https://notcve.org/view.php?id=CVE-2019-0757
A tampering vulnerability exists in the NuGet Package Manager for Linux and Mac that could allow an authenticated attacker to modify a NuGet package's folder structure, aka 'NuGet Package Manager Tampering Vulnerability'. Existe una vulnerabilidad de manipulación en NuGet Package Manager para Linux y Mac que podría permitir que un atacante autenticado modifique la estructura de carpetas de un paquete de NuGet, también conocida como 'NuGet Package Manager Tampering Vulnerability'. A flaw was found in dotnet. A tampering vulnerability exists in NuGet software when executed in a Linux or Mac environment. An attacker who successfully exploits the vulnerability could run arbitrary code in the context of the current user. • https://access.redhat.com/errata/RHSA-2019:1259 https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-0757 https://access.redhat.com/security/cve/CVE-2019-0757 https://bugzilla.redhat.com/show_bug.cgi?id=1685475 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 7.8EPSS: 74%CPEs: 127EXPL: 0CVE-2018-5390 – Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service
https://notcve.org/view.php?id=CVE-2018-5390
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. El kernel de Linux en versiones 4.9 y siguientes pueden forzarse a realizar llamadas muy caras a tcp_collapse_ofo_queue() y tcp_prune_ofo_queue() para cada paquete entrante, lo que puede conducir a una denegación de servicio. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20181031-02-linux-en 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/104976 http://www.securitytracker.com/id/1041424 http://www.securitytracker.com/id/1041434 https://access.redhat.co • CWE-400: Uncontrolled Resource Consumption •

rhnreg_ks in Red Hat Network Client Tools (aka rhn-client-tools) on Red Hat Gluster Storage 2.1 and Enterprise Linux (RHEL) 5, 6, and 7 does not properly validate hostnames in X.509 certificates from SSL servers, which allows remote attackers to prevent system registration via a man-in-the-middle attack. rhnreg_ks en Red Hat Network Client Tools (también conocido como rhn-client-tools) en Red Hat Gluster Storage 2.1 y Enterprise Linux (RHEL) 5, 6 y 7 no valida correctamente los nombres de host en los certificados X.509 de los servidores SSL.

CVSS: 8.1EPSS: 0%CPEs: 85EXPL: 0CVE-2017-13078 – wpa_supplicant: Reinstallation of the group key in the 4-way handshake
https://notcve.org/view.php?id=CVE-2017-13078
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the four-way handshake, allowing an attacker within radio range to replay frames from access points to clients. Wi-Fi Protected Access (WPA y WPA2) permite la reinstalación de la clave temporal GTK (Group Temporal Key) durante la negociación en cuatro pasos, haciendo que un atacante en el rango de radio reproduzca frames desde los puntos de acceso hasta los clientes. A new exploitation technique called key reinstallation attacks (KRACK) affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by reinstalling a previously used group key (GTK) during a 4-way handshake. • http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00024.html http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-007.txt http://www.debian.org/security/2017/dsa-3999 http://www.kb.cert.org/vuls/id/228519 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-a • CWE-323: Reusing a Nonce, Key Pair in Encryption CWE-330: Use of Insufficiently Random Values •
