CVE-2022-27649 – podman: Default inheritable capabilities for linux container should be empty
https://notcve.org/view.php?id=CVE-2022-27649
A flaw was found in Podman, where containers were started incorrectly with non-empty default permissions. A vulnerability was found in Moby (Docker Engine), where containers were started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. Se ha encontrado un fallo en Podman, donde los contenedores eran iniciados incorrectamente con permisos por defecto no vacíos. Se ha encontrado una vulnerabilidad en Moby (Docker Engine), donde los contenedores eran iniciados incorrectamente con capacidades de proceso Linux heredables no vacías. • https://bugzilla.redhat.com/show_bug.cgi?id=2066568 https://github.com/containers/podman/commit/aafa80918a245edcbdaceb1191d749570f1872d0 https://github.com/containers/podman/security/advisories/GHSA-qvf8-p83w-v58j https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4KDETHL5XCT6RZN2BBNOCEXRZ2W3SFU3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DLUJZV3HBP56ADXU6QH2V7RNYUPMVBXQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org • CWE-276: Incorrect Default Permissions •
CVE-2021-3609 – kernel: race condition in net/can/bcm.c leads to local privilege escalation

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-2019-15718 – systemd: systemd-resolved allows unprivileged users to configure DNS
https://notcve.org/view.php?id=CVE-2019-15718
In systemd 240, bus_open_system_watch_bind_with_description in shared/bus-util.c (as used by systemd-resolved to connect to the system D-Bus instance), calls sd_bus_set_trusted, which disables access controls for incoming D-Bus messages. An unprivileged user can exploit this by executing D-Bus methods that should be restricted to privileged users, in order to change the system's DNS resolver settings. En systemd versión 240, la función bus_open_system_watch_bind_with_description en el archivo shared/bus-util.c (como es usado en systemd-resolve para conectarse a la instancia del sistema D-Bus), llama a sd_bus_set_trusted, lo que deshabilita los controles de acceso para los mensajes entrantes de D-Bus. Un usuario no privilegiado puede explotar esto mediante la ejecución de métodos D-Bus que deberían estar restringidos para usuarios con privilegios, para cambiar la configuración de la resolución DNS. An improper authorization flaw was discovered in systemd-resolved in the way it configures the exposed DBus interface org.freedesktop.resolve1. • http://www.openwall.com/lists/oss-security/2019/09/03/1 https://access.redhat.com/errata/RHSA-2019:3592 https://access.redhat.com/errata/RHSA-2019:3941 https://bugzilla.redhat.com/show_bug.cgi?id=1746057 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BRE5IS24XTF5WNZGH2L7GSQJKARBOEGL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HIKGKXZ5OEGOEYURHLJHEMFYNLEGAW5B https://lists.fedoraproject.org/archives/list/package-announce% • CWE-285: Improper Authorization •
CVE-2019-0211 – Apache HTTP Server Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-0211
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. En Apache HTTP Server 2.4, versiones 2.4.17 a 2.4.38, con el evento MPM, worker o prefork, el código ejecutándose en procesos hijo (o hilos) menos privilegiados (incluyendo scripts ejecutados por un intérprete de scripts en proceso) podría ejecutar código arbitrario con los privilegios del proceso padre (normalmente root) manipulando el marcador. Los sistemas que no son Unix no se ven afectados.
