CVSS: 9.3EPSS: 0%CPEs: 13EXPL: 0CVE-2021-3621 – sssd: shell command injection in sssctl
https://notcve.org/view.php?id=CVE-2021-3621
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un fallo en SSSD, donde el comando sssctl era vulnerable a la inyección de comandos de shell por medio de los subcomandos logs-fetch y cache-expire. Este fallo permite a un atacante engañar al usuario root para que ejecute un comando sssctl especialmente diseñado, por ejemplo por medio de sudo, para conseguir acceso de root. • https://bugzilla.redhat.com/show_bug.cgi?id=1975142 https://lists.debian.org/debian-lts-announce/2023/05/msg00028.html https://sssd.io/release-notes/sssd-2.6.0.html https://access.redhat.com/security/cve/CVE-2021-3621 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

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 •

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) •
