CVSS: 8.8EPSS: 0%CPEs: 14EXPL: 0CVE-2019-10167 – libvirt: arbitrary command execution via virConnectGetDomainCapabilities API
https://notcve.org/view.php?id=CVE-2019-10167
The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accepts an "emulatorbin" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges. La API libvirt de la función virConnectGetDomainCapabilities(), versiones 4.x.x anteriores a 4.10.1 y versiones 5.x.x anteriores a 5.4.1, acepta un argumento "emulatorbin" para especificar el programa que proporciona emulación para un dominio. Desde versión v1.2.19, libvirt ejecutará ese programa para examinar las capacidades del dominio. • https://access.redhat.com/libvirt-privesc-vulnerabilities https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10167 https://security.gentoo.org/glsa/202003-18 https://access.redhat.com/security/cve/CVE-2019-10167 https://bugzilla.redhat.com/show_bug.cgi?id=1720117 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-250: Execution with Unnecessary Privileges CWE-284: Improper Access Control CWE-862: Missing Authorization •

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 •
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 •
