CVSS: 7.5EPSS: 5%CPEs: 21EXPL: 1CVE-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 •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 9CVE-2024-1086 – Linux Kernel Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2024-1086
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. Una vulnerabilidad de use after free en el componente netfilter: nf_tables del kernel de Linux puede explotarse para lograr una escalada de privilegios local. La función nft_verdict_init() permite valores positivos como error de eliminación dentro del veredicto del gancho y, por lo tanto, la función nf_hook_slow() puede causar una vulnerabilidad double free cuando NF_DROP se emite con un error de eliminación similar a NF_ACCEPT. Recomendamos actualizar después del compromiso f342de4e2f33e0e39165d8639387aa6c19dff660. A flaw was found in the Netfilter subsystem in the Linux kernel. • https://github.com/Notselwyn/CVE-2024-1086 https://github.com/feely666/CVE-2024-1086 https://github.com/CCIEVoice2009/CVE-2024-1086 https://github.com/pl0xe/CVE-2024-1086 https://github.com/xzx482/CVE-2024-1086 https://github.com/kevcooper/CVE-2024-1086-checker http://www.openwall.com/lists/oss-security/2024/04/10/22 http://www.openwall.com/lists/oss-security/2024/04/10/23 http://www.openwall.com/lists/oss-security/2024/04/14/1 http://www.openwall.co • CWE-416: Use After Free •

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 •

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.
