CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 0CVE-2019-19338 – Kernel: KVM: export MSR_IA32_TSX_CTRL to guest - incomplete fix for TAA (CVE-2019-11135)
https://notcve.org/view.php?id=CVE-2019-19338
A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where, the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-19338 https://software.intel.com/security-software-guidance/insights/deep-dive-intel-transactional-synchronization-extensions-intel-tsx-asynchronous-abort https://www.openwall.com/lists/oss-security/2019/12/10/3 https://access.redhat.com/security/cve/CVE-2019-19338 https://bugzilla.redhat.com/show_bug.cgi?id=1781514 • CWE-203: Observable Discrepancy CWE-385: Covert Timing Channel •
CVSS: 6.1EPSS: 0%CPEs: 3EXPL: 2CVE-2019-19332 – Kernel: kvm: OOB memory write via kvm_dev_ioctl_get_cpuid
https://notcve.org/view.php?id=CVE-2019-19332
An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service. Se encontró un problema de escritura de memoria fuera de límites en el kernel de Linux, versiones 3.13 hasta 5.4, en la manera en que el hipervisor KVM del kernel de Linux manejó la petición "KVM_GET_EMULATED_CPUID" ioctl(2) para obtener las funcionalidades de CPUID emuladas por el hipervisor KVM. Un usuario o proceso capaz de acceder al dispositivo "/dev/kvm" podría usar este fallo para bloquear el sistema, resultando en una denegación de servicio.

https://notcve.org/view.php?id=CVE-2019-13456
In FreeRADIUS 3.0 through 3.0.19, on average 1 in every 2048 EAP-pwd handshakes fails because the password element cannot be found within 10 iterations of the hunting and pecking loop. This leaks information that an attacker can use to recover the password of any user. This information leakage is similar to the "Dragonblood" attack and CVE-2019-9494. En FreeRADIUS versiones 3.0 hasta 3.0.19, en promedio 1 de cada 2048 protocolos de enlace EAP-pwd presenta un fallo porque el elemento de contraseña no puede ser encontrado dentro de las 10 iteraciones del bucle de tipo "hunting and pecking".
