CVSS: 7.8EPSS: 0%CPEs: 32EXPL: 1CVE-2022-27666 – kernel: buffer overflow in IPsec ESP transformation code
https://notcve.org/view.php?id=CVE-2022-27666
A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. Se ha encontrado un fallo de desbordamiento del búfer de la pila en el código de transformación de IPsec ESP en net/ipv4/esp4.c y net/ipv6/esp6.c. Este fallo permite a un atacante local con un privilegio de usuario normal sobrescribir los objetos de la pila del núcleo y puede causar una amenaza de escalada de privilegios local • https://github.com/plummm/CVE-2022-27666 https://bugzilla.redhat.com/show_bug.cgi?id=2061633 https://github.com/torvalds/linux/commit/ebe48d368e97d007bfeb76fcb065d6cfc4c96645 https://security.netapp.com/advisory/ntap-20220429-0001 https://www.debian.org/security/2022/dsa-5127 https://www.debian.org/security/2022/dsa-5173 https://access.redhat.com/security/cve/CVE-2022-27666 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer. ALPACA es un ataque de confusión de contenido de protocolo de capa de aplicación, que explota servidores TLS que implementan diferentes protocolos pero que usan certificados compatibles, como certificados multidominio o comodín. Un atacante de tipo MiTM que tenga acceso al tráfico de la víctima en la capa TCP/IP puede redirigir el tráfico de un subdominio a otro, resultando en a una sesión TLS válida. • https://alpaca-attack.com https://bugzilla.redhat.com/show_bug.cgi?id=1975623 https://lists.debian.org/debian-lts-announce/2022/11/msg00031.html • CWE-295: Improper Certificate Validation •

OpenVPN 2.1 until v2.4.12 and v2.5.6 may enable authentication bypass in external authentication plug-ins when more than one of them makes use of deferred authentication replies, which allows an external user to be granted access with only partially correct credentials. OpenVPN versiones 2.1 hasta v2.4.12 y versión v2.5.6, puede permitir una omisión de autenticación en los complementos de autenticación externa cuando más de uno de ellos hace uso de las respuestas de autenticación diferida, lo que permite que sea concedido acceso a un usuario externo con credenciales sólo parcialmente correctas • https://community.openvpn.net/openvpn/wiki/CVE-2022-0547 https://community.openvpn.net/openvpn/wiki/SecurityAnnouncements https://lists.debian.org/debian-lts-announce/2022/05/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GFXJ35WKPME4HYNQCQNAJHLCZOJL2SAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/R36OYC5SJ6FLPVAYJYYT4MOJ2I7MGYFF https://openvpn.net/community-downloads • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
