CVSS: 6.1EPSS: 0%CPEs: 3EXPL: 0CVE-2020-10751 – kernel: SELinux netlink permission check bypass
https://notcve.org/view.php?id=CVE-2020-10751
A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing. Se detectó un fallo en la implementación del enlace SELinux LSM de kernels de Linux versiones anteriores a 5.7, donde se asumía incorrectamente que un skb solo contendría un único mensaje netlink. El enlace incorrectamente solo comprobaría el primer mensaje netlink en el skb y permitiría o denegaría el resto de los mensajes dentro del skb con el permiso otorgado sin procesamiento adicional. A flaw was found in the Linux kernel’s SELinux LSM hook implementation, where it anticipated the skb would only contain a single Netlink message. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html http://www.openwall.com/lists/oss-security/2020/05/27/3 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10751 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fb73974172ffaaf57a7c42f35424d9aece1a5af6 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce • CWE-345: Insufficient Verification of Data Authenticity CWE-349: Acceptance of Extraneous Untrusted Data With Trusted Data •
CVSS: 5.9EPSS: 0%CPEs: 20EXPL: 0CVE-2020-10711 – Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic
https://notcve.org/view.php?id=CVE-2020-10711
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10711 https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4411-1 https://usn.ubuntu.com/4412-1 https://usn.ubuntu.com/4413-1 https://usn.ubuntu.com/4414-1 https://usn.ubuntu& • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2020-10693
A flaw was found in Hibernate Validator version 6.1.2.Final. A bug in the message interpolation processor enables invalid EL expressions to be evaluated as if they were valid. This flaw allows attackers to bypass input sanitation (escaping, stripping) controls that developers may have put in place when handling user-controlled data in error messages.

A denial of service vulnerability was discovered in nbdkit 1.12.7, 1.14.1 and 1.15.1. An attacker could connect to the nbdkit service and cause it to perform a large amount of work in initializing backend plugins, by simply opening a connection to the service. This vulnerability could cause resource consumption and degradation of service in nbdkit, depending on the plugins configured on the server-side. Se detectó una vulnerabilidad de denegación de servicio en nbdkit versiones 1.12.7, 1.14.1 y 1.15.1. Un atacante podría conectarse al servicio nbdkit y causar que hiciera una gran cantidad de trabajo en la inicialización de plugins de backend, simplemente abriendo una conexión al servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1757258 https://www.redhat.com/archives/libguestfs/2019-September/msg00084.html https://access.redhat.com/security/cve/CVE-2019-14850 • CWE-406: Insufficient Control of Network Message Volume (Network Amplification) •
