CVE-2020-2732 – Kernel: kvm: nVMX: L2 guest may trick the L0 hypervisor to access sensitive L1 resources
https://notcve.org/view.php?id=CVE-2020-2732
A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest. Se detectó un fallo en la manera en que el hipervisor de KVM manejó la emulación de instrucciones para un invitado L2 cuando la virtualización anidada está habilitada. En algunas circunstancias, un invitado L2 puede engañar al invitado L0 para que acceda a recursos L1 confidenciales que deberían estar inaccesibles para el invitado L2. A flaw was found in the way KVM hypervisor handled instruction emulation for the L2 guest when nested(=1) virtualization is enabled. • https://bugzilla.redhat.com/show_bug.cgi?id=1805135 https://git.kernel.org/linus/07721feee46b4b248402133228235318199b05ec https://git.kernel.org/linus/35a571346a94fb93b5b3b6a599675ef3384bc75c https://git.kernel.org/linus/e71237d3ff1abf9f3388337cfebf53b96df2020d https://linux.oracle.com/errata/ELSA-2020-5540.html https://linux.oracle.com/errata/ELSA-2020-5542.html https://linux.oracle.com/errata/ELSA-2020-5543.html https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVE-2020-8945 – proglottis/gpgme: Use-after-free in GPGME bindings during container image pull
https://notcve.org/view.php?id=CVE-2020-8945
The proglottis Go wrapper before 0.1.1 for the GPGME library has a use-after-free, as demonstrated by use for container image pulls by Docker or CRI-O. This leads to a crash or potential code execution during GPG signature verification. El contenedor Proglottis Go versiones anteriores a 0.1.1 para la biblioteca GPGME, presenta un uso de la memoria previamente liberada, como es demostrado por el uso para las extracciones de imágenes de contenedores para Docker o CRI-O. Esto conlleva a un bloqueo o posible ejecución de código durante una comprobación de la firma GPG. A use-after-free vulnerability was found in the Go GPGME wrapper library, github.com/proglottis/gpgme. • https://access.redhat.com/errata/RHSA-2020:0679 https://access.redhat.com/errata/RHSA-2020:0689 https://access.redhat.com/errata/RHSA-2020:0697 https://bugzilla.redhat.com/show_bug.cgi?id=1795838 https://github.com/containers/image/commit/4c7a23f82ef09127b0ff28366d1cf31316dd6cc1 https://github.com/proglottis/gpgme/compare/v0.1.0...v0.1.1 https://github.com/proglottis/gpgme/pull/23 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3SOCLOPTSYABTE4CLTSPDIF • CWE-416: Use After Free •
CVE-2015-5741 – golang: HTTP request smuggling in net/http library
https://notcve.org/view.php?id=CVE-2015-5741
The net/http library in net/http/transfer.go in Go before 1.4.3 does not properly parse HTTP headers, which allows remote attackers to conduct HTTP request smuggling attacks via a request that contains Content-Length and Transfer-Encoding header fields. La biblioteca net/http en el archivo net/http/transfer.go en Go versiones anteriores a 1.4.3, no analiza apropiadamente los encabezados HTTP, lo que permite a atacantes remotos llevar a cabo ataques de tráfico no autorizado de peticiones HTTP por medio de una petición que contiene campos de encabezado Content-Length y Transfer-Encoding . HTTP-request vulnerabilities have been found in the Golang net/http and net/textproto libraries. Request headers with double Content-Length fields do not generate a 400 error (the second field is ignored), and invalid fields are parsed as valid (for example, "Content Length:" with a space in the middle is accepted). A non-authenticated attacker could exploit these flaws to bypass security controls, perform web-cache poisoning, or alter the request/response map (denial of service). • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/167997.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168029.html http://seclists.org/oss-sec/2015/q3/237 http://seclists.org/oss-sec/2015/q3/292 http://seclists.org/oss-sec/2015/q3/294 https://bugzilla.redhat.com/show_bug.cgi?id=1250352 https://github.com/golang/go/commit/300d9a21583e7cf0149a778a0611e76ff7c6680f https://access.redhat.com/security/cve/CVE-2015-5741 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
