CVE-2023-52160 – wpa_supplicant: potential authorization bypass
https://notcve.org/view.php?id=CVE-2023-52160
The implementation of PEAP in wpa_supplicant through 2.10 allows authentication bypass. For a successful attack, wpa_supplicant must be configured to not verify the network's TLS certificate during Phase 1 authentication, and an eap_peap_decrypt vulnerability can then be abused to skip Phase 2 authentication. The attack vector is sending an EAP-TLV Success packet instead of starting Phase 2. This allows an adversary to impersonate Enterprise Wi-Fi networks. La implementación de PEAP en wpa_supplicant hasta la versión 2.10 permite omitir la autenticación. • https://lists.debian.org/debian-lts-announce/2024/02/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/N46C4DTVUWK336OYDA4LGALSC5VVPTCC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QU6IR4KV3ZXJZLK2BY7HAHGZNCP7FPNI https://w1.fi/cgit/hostap/commit/?id=8e6485a1bcb0baffdea9e55255a81270b768439c https://www.top10vpn.com/research/wifi-vulnerabilities https://access.redhat.com/security/cve/CVE-2023-52160 https://bugzilla.redhat.com/ • CWE-285: Improper Authorization CWE-287: Improper Authentication •
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-2024-1048 – Grub2: grub2-set-bootflag can be abused by local (pseudo-)users
https://notcve.org/view.php?id=CVE-2024-1048
A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks. Se encontró una falla en la utilidad grub2-set-bootflag de grub2. Después de la corrección de CVE-2019-14865, grub2-set-bootflag creará un archivo temporal con el nuevo contenido de grubenv y le cambiará el nombre al archivo grubenv original. • http://www.openwall.com/lists/oss-security/2024/02/06/3 https://access.redhat.com/errata/RHSA-2024:2456 https://access.redhat.com/errata/RHSA-2024:3184 https://access.redhat.com/security/cve/CVE-2024-1048 https://bugzilla.redhat.com/show_bug.cgi?id=2256827 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XRZQCVZ3XOASVFT6XLO7F2ZXOLOHIJZQ https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/YSJAEGRR3XHMBBBKYOVMII4P34IXEYPE https: • CWE-459: Incomplete Cleanup •

CVE-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 https://github.com/matrixvk/CVE-2024-1086-aarch64 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& • CWE-416: Use After Free •
