CVSS: 5.9EPSS: 0%CPEs: 23EXPL: 0CVE-2023-4813 – Glibc: potential use-after-free in gaih_inet()
https://notcve.org/view.php?id=CVE-2023-4813
A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. Se encontró una falla en glibc. En una situación poco común, la función gaih_inet puede utilizar memoria que se ha liberado, lo que provoca un bloqueo de la aplicación. • http://www.openwall.com/lists/oss-security/2023/10/03/8 https://access.redhat.com/errata/RHSA-2023:5453 https://access.redhat.com/errata/RHSA-2023:5455 https://access.redhat.com/errata/RHSA-2023:7409 https://access.redhat.com/security/cve/CVE-2023-4813 https://bugzilla.redhat.com/show_bug.cgi?id=2237798 https://security.netapp.com/advisory/ntap-20231110-0003 • CWE-416: Use After Free •
CVSS: 6.5EPSS: 0%CPEs: 9EXPL: 0CVE-2023-38201 – Keylime: challenge-response protocol bypass during agent registration
https://notcve.org/view.php?id=CVE-2023-38201
A flaw was found in the Keylime registrar that could allow a bypass of the challenge-response protocol during agent registration. This issue may allow an attacker to impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database. Se encontró una falla en el registrador de Keylime que podría permitir una omisión del protocolo de desafío-respuesta durante el registro del agente. Este problema puede permitir a un atacante suplantar a un agente y ocultar el verdadero estado de un equipo supervisado si un usuario legítimo agrega el agente falso a la lista de verificadores, lo que provoca una violación de la integridad de la base de datos del registrador. • https://access.redhat.com/errata/RHSA-2023:5080 https://access.redhat.com/security/cve/CVE-2023-38201 https://bugzilla.redhat.com/show_bug.cgi?id=2222693 https://github.com/keylime/keylime/commit/9e5ac9f25cd400b16d5969f531cee28290543f2a https://github.com/keylime/keylime/security/advisories/GHSA-f4r5-q63f-gcww https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ZIZZB5NHNCS5D2AEH3ZAO6OQC72IK7WS • CWE-639: Authorization Bypass Through User-Controlled Key •
CVSS: 7.8EPSS: 0%CPEs: 58EXPL: 0CVE-2023-3899 – Subscription-manager: inadequate authorization of com.redhat.rhsm1 d-bus interface allows local users to modify configuration
https://notcve.org/view.php?id=CVE-2023-3899
A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root. • https://access.redhat.com/errata/RHSA-2023:4701 https://access.redhat.com/errata/RHSA-2023:4702 https://access.redhat.com/errata/RHSA-2023:4703 https://access.redhat.com/errata/RHSA-2023:4704 https://access.redhat.com/errata/RHSA-2023:4705 https://access.redhat.com/errata/RHSA-2023:4706 https://access.redhat.com/errata/RHSA-2023:4707 https://access.redhat.com/errata/RHSA-2023:4708 https://access.redhat.com/security/cve/CVE-2023-3899 https://bugzilla.redhat.com/show • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •

CVSS: 7.8EPSS: 0%CPEs: 35EXPL: 0CVE-2023-0494 – X.Org Server DeepCopyPointerClasses Use-After-Free Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-0494
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DeepCopyPointerClasses function. • https://bugzilla.redhat.com/show_bug.cgi?id=2165995 https://gitlab.freedesktop.org/xorg/xserver/-/commit/0ba6d8c37071131a49790243cdac55392ecf71ec https://lists.x.org/archives/xorg-announce/2023-February/003320.html https://security.gentoo.org/glsa/202305-30 https://access.redhat.com/security/cve/CVE-2023-0494 • CWE-416: Use After Free •
