CVE-2019-14870
https://notcve.org/view.php?id=CVE-2019-14870
All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. Todas las versiones de Samba 4.xx anteriores a 4.9.17, versiones 4.10.x anteriores a 4.10.11 y versiones 4.11.x anteriores a 4.11.3, presentan un problema, donde el modelo de delegación de Kerberos S4U (MS-SFU) incluye una funcionalidad que permite a un subconjunto de clientes ser excluidos de la delegación restringida de cualquier manera, ya sea S4U2Self o autenticación Kerberos regular, al forzar que todos los tickets para estos clientes no sean reenviables. En AD, esto es implementado mediante un atributo de usuario delegation_not_allowed (también se conoce como no delegado), que se traduce como no permitido-reenviable. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14870 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2022/11/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE https: • CWE-285: Improper Authorization CWE-287: Improper Authentication •
CVE-2019-19448
https://notcve.org/view.php?id=CVE-2019-19448
In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure. En el kernel de Linux versiones 5.0.21 y 5.3.11, montando una imagen de sistema de archivos btrfs diseñada, al realizar algunas operaciones y luego haciendo una llamada de sistema syncfs puede conllevar a un uso de la memoria previamente liberada en la función try_merge_free_space en el archivo fs/btrfs/free-space-cache.c porque el puntero en una estructura de datos izquierda puede ser el mismo que el puntero en una estructura de datos derecha. • https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19448 https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/2020/10/msg00034.html https://security.netapp.com/advisory/ntap-20200103-0001 https://usn.ubuntu.com/4578-1 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2019-19524
In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. En el kernel de Linux versiones anteriores a 5.3.12, se presenta un bug de uso de la memoria previamente liberada que puede ser causado por un dispositivo USB malicioso en el controlador del archivo drivers/input/ff-memless.c, también se conoce como CID-fa3a5a1880c9. A use-after-free flaw was found in the Linux kernel’s input device driver functionality when unplugging a device. A user with physical access could use this flaw to crash the system. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/12/03/4 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.12 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fa3a5a1880c91bb92594ad42dfe9eedad7996b86 https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https:/ • CWE-416: Use After Free •

CVE-2019-19534 – kernel: information leak bug caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver
https://notcve.org/view.php?id=CVE-2019-19534
In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. En el kernel de Linux versiones anteriores a 5.3.11, hay un bug de filtrado de información que puede ser causado por un dispositivo USB malicioso en el controlador del archivo drivers/net/can/usb/peak_usb/pcan_usb_core.c, también se conoce como CID-f7a1337f0d29. An information-leak flaw was found in the Linux kernel's pcan USB driver. When a device using this driver connects to the system, the stack information is leaked to the CAN bus, a controller area network for automobiles. The highest threat with this vulnerability is breach of data confidentiality. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://www.openwall.com/lists/oss-security/2019/12/03/4 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.11 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f7a1337f0d29b98733c8824e165fca3371d7d4fd https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://usn.ubuntu.com/4225-1 https& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-909: Missing Initialization of Resource •
