CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-3513 – keycloak: Brute force attack is possible even after the account lockout
https://notcve.org/view.php?id=CVE-2021-3513
A flaw was found in keycloak where a brute force attack is possible even when the permanent lockout feature is enabled. This is due to a wrong error message displayed when wrong credentials are entered. The highest threat from this vulnerability is to confidentiality. Se ha encontrado un fallo en keycloak por el que es posible realizar un ataque de fuerza bruta incluso cuando la función de bloqueo permanente está habilitada. Esto es debido a un mensaje de error que es mostrado cuando son introducidos credenciales incorrectas. • https://access.redhat.com/security/cve/CVE-2021-3513 https://bugzilla.redhat.com/show_bug.cgi?id=1953439 • CWE-209: Generation of Error Message Containing Sensitive Information CWE-522: Insufficiently Protected Credentials •
CVSS: 8.8EPSS: 0%CPEs: 76EXPL: 1CVE-2021-3656 – kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)
https://notcve.org/view.php?id=CVE-2021-3656
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. Se ha encontrado un fallo en el código AMD de KVM para soportar la virtualización anidada SVM. • https://github.com/rami08448/CVE-2021-3656-Demo https://bugzilla.redhat.com/show_bug.cgi?id=1983988 https://git.kernel.org/pub/scm/virt/kvm/kvm.git/commit/?id=c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://github.com/torvalds/linux/commit/c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://www.openwall.com/lists/oss-security/2021/08/16/1 https://access.redhat.com/security/cve/CVE-2021-3656 • CWE-862: Missing Authorization •

https://notcve.org/view.php?id=CVE-2021-3597
A flaw was found in undertow. The HTTP2SourceChannel fails to write the final frame under some circumstances, resulting in a denial of service. The highest threat from this vulnerability is availability. This flaw affects Undertow versions prior to 2.0.35.SP1, prior to 2.2.6.SP1, prior to 2.2.7.SP1, prior to 2.0.36.SP1, prior to 2.2.9.Final and prior to 2.0.39.Final.

https://notcve.org/view.php?id=CVE-2021-3644
A flaw was found in wildfly-core in all versions. If a vault expression is in the form of a single attribute that contains multiple expressions, a user who was granted access to the management interface can potentially access a vault expression they should not be able to access and possibly retrieve the item which was stored in the vault. The highest threat from this vulnerability is data confidentiality and integrity. Se ha encontrado un fallo en wildfly-core en todas las versiones. Si una expresión de bóveda está en la forma de un solo atributo que contiene múltiples expresiones, un usuario al que le ha sido concedido acceso a la interfaz de administración puede potencialmente acceder a una expresión de bóveda a la que no debería poder acceder y posiblemente recuperar el elemento que estaba almacenado en la bóveda. • https://access.redhat.com/security/cve/CVE-2021-3644 https://bugzilla.redhat.com/show_bug.cgi?id=1976052 https://github.com/wildfly/wildfly-core/commit/06dd9884f6ba50470b1fb5a35198a8784f037714 https://github.com/wildfly/wildfly-core/commit/6d8db43cd43b5994b7a14003db978064e086090b https://github.com/wildfly/wildfly-core/pull/4668 https://issues.redhat.com/browse/WFCORE-5511 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2021-3653
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to 5.14-rc7. • http://packetstormsecurity.com/files/165477/Kernel-Live-Patch-Security-Notice-LSN-0083-1.html https://bugzilla.redhat.com/show_bug.cgi?id=1983686 https://lists.debian.org/debian-lts-announce/2021/10/msg00010.html https://lists.debian.org/debian-lts-announce/2021/12/msg00012.html https://www.openwall.com/lists/oss-security/2021/08/16/1 https://access.redhat.com/security/cve/CVE-2021-3653 • CWE-862: Missing Authorization •
