CVE-2020-10756 – QEMU SLiRP Networking Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-10756
An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1. Se encontró una vulnerabilidad de lectura fuera de límites en la implementación de red SLiRP del emulador QEMU. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00040.html https://bugzilla.redhat.com/show_bug.cgi?id=1835986 https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JYTZ32P67PZER6P7TW6FQK3SZRKQLVEI https://security.netapp.com/advisory/ntap-20201001-0001 https://usn.ubuntu.com/4437-1 https://usn.ubuntu.com/ • CWE-125: Out-of-bounds Read •
CVE-2020-10759 – fwupd: Possible bypass in signature verification
https://notcve.org/view.php?id=CVE-2020-10759
A PGP signature bypass flaw was found in fwupd (all versions), which could lead to the installation of unsigned firmware. As per upstream, a signature bypass is theoretically possible, but not practical because the Linux Vendor Firmware Service (LVFS) is either not implemented or enabled in versions of fwupd shipped with Red Hat Enterprise Linux 7 and 8. The highest threat from this vulnerability is to confidentiality and integrity. Se encontró un fallo de omisión de la firma PGP en fwupd (todas las versiones), que podría conllevar a la instalación de firmware sin firmar. Según aguas arriba, teóricamente es posible omitir la firma, pero no es práctico porque el Linux Vendor Firmware Service (LVFS) no está implementado o habilitado en las versiones de fwupd enviadas con Red Hat Enterprise Linux versiones 7 y 8. • https://github.com/justinsteven/CVE-2020-10759-poc https://bugzilla.redhat.com/show_bug.cgi?id=1844316 https://github.com/justinsteven/advisories/blob/master/2020_fwupd_dangling_s3_bucket_and_CVE-2020-10759_signature_verification_bypass.md https://access.redhat.com/security/cve/CVE-2020-10759 • CWE-347: Improper Verification of Cryptographic Signature •

CVE-2020-10749 – containernetworking/plugins: IPv6 router advertisements allow for MitM attacks on IPv4 clusters
https://notcve.org/view.php?id=CVE-2020-10749
A vulnerability was found in all versions of containernetworking/plugins before version 0.8.6, that allows malicious containers in Kubernetes clusters to perform man-in-the-middle (MitM) attacks. A malicious container can exploit this flaw by sending rogue IPv6 router advertisements to the host or other containers, to redirect traffic to the malicious container. Se detectó una vulnerabilidad en todas las versiones de containernetworking/plugins versiones anteriores a 0.8.6, que permite a contenedores maliciosos en los grupos de Kubernetes llevar a cabo ataques de tipo man-in-the-middle (MitM). Un contenedor malicioso puede explotar este fallo mediante el envío de anuncios de enrutadores IPv6 falsos al host u otros contenedores, para redireccionar el tráfico al contenedor malicioso.
