CVE-2019-1125 – Windows Kernel Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-1125
An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information that could be used to try to compromise the affected system further. On January 3, 2018, Microsoft released an advisory and security updates related to a newly-discovered class of hardware vulnerabilities (known as Spectre) involving speculative execution side channels that affect AMD, ARM, and Intel CPUs to varying degrees. This vulnerability, released on August 6, 2019, is a variant of the Spectre Variant 1 speculative execution side channel vulnerability and has been assigned CVE-2019-1125. Microsoft released a security update on July 9, 2019 that addresses the vulnerability through a software change that mitigates how the CPU speculatively accesses memory. Note that this vulnerability does not require a microcode update from your device OEM. • https://www.exploit-db.com/exploits/48071 http://packetstormsecurity.com/files/156337/SWAPGS-Attack-Proof-Of-Concept.html http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200408-01-swapgs-en https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHBA-2019:3248 https://access.redhat.com/errata/RHSA-2019:2600 https://access.redhat.com/errata/RHSA-2019:2609 https://access.redhat.com/errata/RHSA-2019:2695 https://access.redhat.com/errata/RHS • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2019-10161 – libvirt: arbitrary file read/exec via virDomainSaveImageGetXMLDesc API
https://notcve.org/view.php?id=CVE-2019-10161
It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs. Se detectó que libvirtd anterior a versiones 4.10.1 y 5.4.1, permitiría a clientes de solo lectura usar la API de la función virDomainSaveImageGetXMLDesc(), especificando una ruta (path) arbitraria a la que se accedería con los permisos del proceso libvirtd. Un atacante con acceso al socket libvirtd podría usar esto para probar la existencia de archivos arbitrarios, causar una denegación de servicio o causar que libvirtd ejecute programas arbitrarios. It was discovered that libvirtd would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. • https://access.redhat.com/libvirt-privesc-vulnerabilities https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10161 https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=aed6a032cead4386472afb24b16196579e239580 https://security.gentoo.org/glsa/202003-18 https://usn.ubuntu.com/4047-2 https://access.redhat.com/security/cve/CVE-2019-10161 https://bugzilla.redhat.com/show_bug.cgi?id=1720115 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-284: Improper Access Control CWE-862: Missing Authorization •
CVE-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 •

CVE-2019-3460 – kernel: Heap address information leak while using L2CAP_PARSE_CONF_RSP
https://notcve.org/view.php?id=CVE-2019-3460
A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found in the Linux kernel before 5.1-rc1. Se ha descubierto una fuga de información en múltiples ubicaciones en memoria dinámica, incluyendo L2CAP_GET_CONF_OPT en el kernel de Linux anterior a 5.1-rc1. A flaw was found in the Linux kernel's implementation of logical link control and adaptation protocol (L2CAP), part of the Bluetooth stack in the l2cap_parse_conf_rsp and l2cap_parse_conf_req functions. An attacker with physical access within the range of standard Bluetooth transmission can create a specially crafted packet. The response to this specially crafted packet can contain part of the kernel stack which can be used in a further attack. • http://www.openwall.com/lists/oss-security/2019/06/27/2 http://www.openwall.com/lists/oss-security/2019/06/27/7 http://www.openwall.com/lists/oss-security/2019/06/28/1 http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/08/12/1 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat. • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
