CVSS: 9.0EPSS: 0%CPEs: 33EXPL: 0CVE-2020-25719 – samba: Samba AD DC did not always rely on the SID and PAC in Kerberos tickets
https://notcve.org/view.php?id=CVE-2020-25719
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. Se encontró un fallo en la forma en que Samba, como controlador de dominio de Active Directory, implementaba la autenticación basada en nombres de Kerberos. El AD DC de Samba, podía confundirse sobre el usuario que representa un ticket si no requería estrictamente un PAC de Kerberos y siempre usaba los SIDs encontrados dentro. • https://bugzilla.redhat.com/show_bug.cgi?id=2019732 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2020-25719.html https://access.redhat.com/security/cve/CVE-2020-25719 • CWE-287: Improper Authentication CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
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 •

CVSS: 5.8EPSS: 81%CPEs: 84EXPL: 2CVE-2016-3715 – ImageMagick Arbitrary File Deletion Vulnerability
https://notcve.org/view.php?id=CVE-2016-3715
The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image. El codificador EPHEMERAL en ImageMagick en versiones anteriores a 6.9.3-10 y 7.x en versiones anteriores a 7.0.1-1 permite a atacantes remotos eliminar archivos arbitrarios a través de una imagen manipulada. It was discovered that certain ImageMagick coders and pseudo-protocols did not properly prevent security sensitive operations when processing specially crafted images. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would allow the attacker to delete arbitrary files. ImageMagick contains an unspecified vulnerability that could allow users to delete files by using ImageMagick's 'ephemeral' pseudo protocol, which deletes files after reading. • https://www.exploit-db.com/exploits/39767 http://git.imagemagick.org/repos/ImageMagick/blob/a01518e08c840577cabd7d3ff291a9ba735f7276/ChangeLog http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00051.html http&# • CWE-20: Improper Input Validation •
