CVSS: 8.1EPSS: 0%CPEs: 371EXPL: 0CVE-2019-9506 – Blutooth BR/EDR specification does not specify sufficient encryption key length and allows an attacker to influence key length negotiation
https://notcve.org/view.php?id=CVE-2019-9506
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing. La especificación de Bluetooth BR/EDR incluyendo versión 5.1, permite una longitud de clave de cifrado suficientemente baja y no impide que un atacante influya en la negociación de longitud de clave. Esto permite ataques prácticos de fuerza bruta (también se conoce como "KNOB") que pueden descifrar el tráfico e inyectar texto cifrado arbitrario sin que la víctima se dé cuenta. A flaw was discovered in the Bluetooth protocol. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00037.html http://seclists.org/fulldisclosure/2019/Aug/11 http://seclists.org/fulldisclosure/2019/Aug/13 http://seclists.org/fulldisclosure/2019/Aug/14 http://seclists.org/fulldisclosure/2019/Aug/15 http://www.cs.ox.ac.uk/publications/publication12404-abstract.html http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20190828-01-knob-en https: • CWE-310: Cryptographic Issues CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVSS: 7.5EPSS: 0%CPEs: 30EXPL: 0CVE-2018-16871 – kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence
https://notcve.org/view.php?id=CVE-2018-16871
A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost. Se detectó un fallo en la implementación de NFS del kernel de Linux, todas las versiones 3.x y todas las versiones 4.x hasta 4.20. • https://access.redhat.com/errata/RHSA-2019:2696 https://access.redhat.com/errata/RHSA-2019:2730 https://access.redhat.com/errata/RHSA-2020:0740 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16871 https://security.netapp.com/advisory/ntap-20211004-0002 https://support.f5.com/csp/article/K18657134 https://support.f5.com/csp/article/K18657134?utm_source=f5support&%3Butm_medium=RSS https://access.redhat.com/security/cve/CVE-2018-16871 https://bugzilla.redhat.com/show_b • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2019-3459
A heap address information leak while using L2CAP_GET_CONF_OPT was discovered in the Linux kernel before 5.1-rc1. Se descubrió una fuga de información de direcciones en memoria dinámica mientras se usaba L2CAP_GET_CONF_OPT en el kernel de Linux anterior a 5.1-rc1. A flaw was found in the Linux kernel's implementation of Logical Link Control and Adaptation Protocol (L2CAP), part of the Bluetooth stack. An attacker, within the range of standard Bluetooth transmissions, can create and send a specially crafted packet. The response to this specially crafted packet can contain part of the kernel stack which can be used in a further attack. • http://www.openwall.com/lists/oss-security/2019/06/27/2 http://www.openwall.com/lists/oss-security/2019/06/27/7 http://www.openwall.com/lists/oss-security/2019/06/28/1 http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/08/12/1 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat. • CWE-125: Out-of-bounds Read CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
