CVSS: 9.3EPSS: 0%CPEs: 3EXPL: 1CVE-2020-8933 – Priviged Escalation in Google Cloud Platform's Guest-OSLogin
https://notcve.org/view.php?id=CVE-2020-8933
A vulnerability in Google Cloud Platform's guest-oslogin versions between 20190304 and 20200507 allows a user that is only granted the role "roles/compute.osLogin" to escalate privileges to root. Using the membership to the "lxd" group, an attacker can attach host devices and filesystems. Within an lxc container, it is possible to attach the host OS filesystem and modify /etc/sudoers to then gain administrative privileges. All images created after 2020-May-07 (20200507) are fixed, and if you cannot update, we recommend you edit /etc/group/security.conf and remove the "lxd" user from the OS Login entry.

https://notcve.org/view.php?id=CVE-2020-8903
A vulnerability in Google Cloud Platform's guest-oslogin versions between 20190304 and 20200507 allows a user that is only granted the role "roles/compute.osLogin" to escalate privileges to root. Using their membership to the "adm" group, users with this role are able to read the DHCP XID from the systemd journal. Using the DHCP XID, it is then possible to set the IP address and hostname of the instance to any value, which is then stored in /etc/hosts. An attacker can then point metadata.google.internal to an arbitrary IP address and impersonate the GCE metadata server which make it is possible to instruct the OS Login PAM module to grant administrative privileges. All images created after 2020-May-07 (20200507) are fixed, and if you cannot update, we recommend you edit /etc/group/security.conf and remove the "adm" user from the OS Login entry. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00047.html https://cloud.google.com/support/bulletins/#gcp-2020-008 https://github.com/GoogleCloudPlatform/guest-oslogin/pull/29 https://gitlab.com/gitlab-com/gl-security/gl-redteam/red-team-tech-notes/-/tree/master/oslogin-privesc-june-2020 • CWE-276: Incorrect Default Permissions •

A vulnerability in Google Cloud Platform's guest-oslogin versions between 20190304 and 20200507 allows a user that is only granted the role "roles/compute.osLogin" to escalate privileges to root. Using their membership to the "docker" group, an attacker with this role is able to run docker and mount the host OS. Within docker, it is possible to modify the host OS filesystem and modify /etc/groups to gain administrative privileges.

CVSS: 5.5EPSS: 0%CPEs: 7EXPL: 0CVE-2020-11095 – Global OOB read in update_recv_primary_order in FreeRDP
https://notcve.org/view.php?id=CVE-2020-11095
In FreeRDP before version 2.1.2, an out of bound reads occurs resulting in accessing a memory location that is outside of the boundaries of the static array PRIMARY_DRAWING_ORDER_FIELD_BYTES. This is fixed in version 2.1.2. En FreeRDP versiones anteriores a 2.1.2, se producen lecturas fuera de límite que resultan en el acceso a una ubicación de memoria que está fuera de límites de la matriz estática de PRIMARY_DRAWING_ORDER_FIELD_BYTES. Esto es corregido en la versión 2.1.2 • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00080.html http://www.freerdp.com/2020/06/22/2_1_2-released https://github.com/FreeRDP/FreeRDP/commit/733ee3208306b1ea32697b356c0215180fc3f049 https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-563r-pvh7-4fw2 https://lists.debian.org/debian-lts-announce/2023/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6Y35HBHG2INICLSGCIKNAR7GCXEHQACQ https://lists.fedoraproject.org/archives/list&#x • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2020-11096
In FreeRDP before version 2.1.2, there is a global OOB read in update_read_cache_bitmap_v3_order. As a workaround, one can disable bitmap cache with -bitmap-cache (default). This is fixed in version 2.1.2. En FreeRDP versiones anteriores a 2.1.2, se presenta una lectura OOB global en update_read_cache_bitmap_v3_order. Como solución alternativa, se puede deshabilitar la memoria caché de mapa de bits con -bitmap-cache (predeterminado). • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00080.html http://www.freerdp.com/2020/06/22/2_1_2-released https://github.com/FreeRDP/FreeRDP/commit/b8beb55913471952f92770c90c372139d78c16c0 https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-mjw7-3mq2-996x https://lists.debian.org/debian-lts-announce/2023/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6Y35HBHG2INICLSGCIKNAR7GCXEHQACQ https://lists.fedoraproject.org/archives/list&#x • CWE-125: Out-of-bounds Read •
