CVE-2023-50387 – bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator
https://notcve.org/view.php?id=CVE-2023-50387
Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. Ciertos aspectos DNSSEC del protocolo DNS (en RFC 4035 y RFC relacionados) permiten a atacantes remotos provocar una denegación de servicio (consumo de CPU) a través de una o más respuestas DNSSEC cuando hay una zona con muchos registros DNSKEY y RRSIG, también conocido como "KeyTrap". " asunto. La especificación del protocolo implica que un algoritmo debe evaluar todas las combinaciones de registros DNSKEY y RRSIG. Processing specially crafted responses coming from DNSSEC-signed zones can lead to uncontrolled CPU usage, leading to a Denial of Service in the DNSSEC-validating resolver side. This vulnerability applies only for systems where DNSSEC validation is enabled. • https://github.com/knqyf263/CVE-2023-50387 http://www.openwall.com/lists/oss-security/2024/02/16/2 http://www.openwall.com/lists/oss-security/2024/02/16/3 https://access.redhat.com/security/cve/CVE-2023-50387 https://bugzilla.suse.com/show_bug.cgi?id=1219823 https://docs.powerdns.com/recursor/security-advisories/powerdns-advisory-2024-01.html https://gitlab.nic.cz/knot/knot-resolver/-/releases/v5.7.1 https://kb.isc.org/docs/cve-2023-50387 https://lists • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2024-0408 – Xorg-x11-server: selinux unlabeled glx pbuffer
https://notcve.org/view.php?id=CVE-2024-0408
A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL. Se encontró una falla en el servidor X.Org. El código GLX PBuffer no llama al gancho XACE al crear el búfer, dejándolo sin etiquetar. • https://access.redhat.com/errata/RHSA-2024:0320 https://access.redhat.com/errata/RHSA-2024:2169 https://access.redhat.com/errata/RHSA-2024:2170 https://access.redhat.com/errata/RHSA-2024:2995 https://access.redhat.com/errata/RHSA-2024:2996 https://access.redhat.com/security/cve/CVE-2024-0408 https://bugzilla.redhat.com/show_bug.cgi?id=2257689 https://lists.debian.org/debian-lts-announce/2024/01/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce@lists& • CWE-158: Improper Neutralization of Null Byte or NUL Character •
CVE-2024-0409 – Xorg-x11-server: selinux context corruption
https://notcve.org/view.php?id=CVE-2024-0409
A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context. Se encontró una falla en el servidor X.Org. El código del cursor tanto en Xephyr como en Xwayland utiliza el tipo incorrecto de privado en el momento de la creación. • https://access.redhat.com/errata/RHSA-2024:0320 https://access.redhat.com/errata/RHSA-2024:2169 https://access.redhat.com/errata/RHSA-2024:2170 https://access.redhat.com/errata/RHSA-2024:2995 https://access.redhat.com/errata/RHSA-2024:2996 https://access.redhat.com/security/cve/CVE-2024-0409 https://bugzilla.redhat.com/show_bug.cgi?id=2257690 https://lists.debian.org/debian-lts-announce/2024/01/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce@lists& • CWE-787: Out-of-bounds Write •
