CVSS: 5.9EPSS: 0%CPEs: 4EXPL: 0CVE-2020-11934 – Sandbox escape vulnerability via snapctl user-open (xdg-open)
https://notcve.org/view.php?id=CVE-2020-11934
It was discovered that snapctl user-open allowed altering the $XDG_DATA_DIRS environment variable when calling the system xdg-open. OpenURL() in usersession/userd/launcher.go would alter $XDG_DATA_DIRS to append a path to a directory controlled by the calling snap. A malicious snap could exploit this to bypass intended access restrictions to control how the host system xdg-open script opens the URL and, for example, execute a script shipped with the snap without confinement. This issue did not affect Ubuntu Core systems. Fixed in snapd versions 2.45.1ubuntu0.2, 2.45.1+18.04.2 and 2.45.1+20.04.2. • https://launchpad.net/bugs/1880085 https://ubuntu.com/USN-4424-1 • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 6.9EPSS: 0%CPEs: 4EXPL: 0CVE-2019-20908 – kernel: lockdown: bypass through ACPI write via efivar_ssdt
https://notcve.org/view.php?id=CVE-2019-20908
An issue was discovered in drivers/firmware/efi/efi.c in the Linux kernel before 5.4. Incorrect access permissions for the efivar_ssdt ACPI variable could be used by attackers to bypass lockdown or secure boot restrictions, aka CID-1957a85b0032. Se detectó un problema en el archivo drivers/firmware/efi/efi.c en el kernel de Linux versiones anteriores a 5.4. Permisos de acceso incorrectos para la variable efivar_ssdt ACPI podrían ser usados por atacantes para omitir el bloqueo o asegurar las restricciones de arranque, también se conoce como CID-1957a85b0032 A flaw was found in how the ACPI table loading through the EFI variable (and the related efivar_ssdt boot option) was handled when the Linux kernel was locked down. This flaw allows a (root) privileged local user to circumvent the kernel lockdown restrictions. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html http://www.openwall.com/lists/oss-security/2020/07/20/6 http://www.openwall.com/lists/oss-security/2020/07/29/3 http://www.openwall.com/lists/oss-security/2020/07/30/2 http://www.openwall.com/lists/oss-security/2020/07/30/3 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1957a85b0032a81e6482ca4aa • CWE-284: Improper Access Control •
