CVE-2020-25657 – m2crypto: bleichenbacher timing attacks in the RSA decryption API
https://notcve.org/view.php?id=CVE-2020-25657
A flaw was found in all released versions of m2crypto, where they are vulnerable to Bleichenbacher timing attacks in the RSA decryption API via the timed processing of valid PKCS#1 v1.5 Ciphertext. The highest threat from this vulnerability is to confidentiality. Se encontró un fallo en todas las versiones publicadas de m2crypto, donde son vulnerables a ataques de sincronización de Bleichenbacher en la API de descifrado RSA por medio del procesamiento cronometrado de texto cifrado PKCS#1 versión v1.5 válido. La mayor amenaza de esta vulnerabilidad es la confidencialidad • https://bugzilla.redhat.com/show_bug.cgi?id=1889823 https://access.redhat.com/security/cve/CVE-2020-25657 • CWE-203: Observable Discrepancy CWE-385: Covert Timing Channel •
CVE-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 •
CVE-2019-14850 – nbdkit: denial of service due to premature opening of back-end connection
https://notcve.org/view.php?id=CVE-2019-14850
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) •

CVE-2019-14818 – dpdk: possible memory leak leads to denial of service
https://notcve.org/view.php?id=CVE-2019-14818
A flaw was found in all dpdk version 17.x.x before 17.11.8, 16.x.x before 16.11.10, 18.x.x before 18.11.4 and 19.x.x before 19.08.1 where a malicious master, or a container with access to vhost_user socket, can send specially crafted VRING_SET_NUM messages, resulting in a memory leak including file descriptors. This flaw could lead to a denial of service condition. Se encontró un fallo en todas las versiones de dpdk 17.xx anteriores a 17.11.8, versiones 16.xx anteriores a 16.11.10, versiones 18.xx anteriores a 18.11.4 y versiones 19.xx anteriores a 19.08.1, donde un maestro malicioso o un contenedor con acceso al socket vhost_user, puede enviar mensajes de VRING_SET_NUM especialmente diseñados, resultando en una pérdida de memoria incluyendo descriptores de archivo.
