CVSS: 7.5EPSS: 11%CPEs: 9EXPL: 4CVE-2022-3602 – X.509 Email Address 4-byte Buffer Overflow
https://notcve.org/view.php?id=CVE-2022-3602
A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. • https://github.com/colmmacc/CVE-2022-3602 https://github.com/eatscrayon/CVE-2022-3602-poc https://github.com/corelight/CVE-2022-3602 https://github.com/cybersecurityworks553/CVE-2022-3602-and-CVE-2022-3786 http://packetstormsecurity.com/files/169687/OpenSSL-Security-Advisory-20221101.html http://www.openwall.com/lists/oss-security/2022/11/01/15 http://www.openwall.com/lists/oss-security/2022/11/01/16 http://www.openwall.com/lists/oss-security/2022/11/01/17 http://www&# • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

A flaw was found in http-proxy-agent, prior to version 2.1.0. It was discovered http-proxy-agent passes an auth option to the Buffer constructor without proper sanitization. This could result in a Denial of Service through the usage of all available CPU resources and data exposure through an uninitialized memory leak in setups where an attacker could submit typed input to the auth parameter. Se encontró un fallo en http-proxy-agent, versiones anteriores a 2.1.0. Se detectó que http-proxy-agent pasa una opción de autenticación al constructor de Buffer sin un saneamiento apropiado. • https://bugzilla.redhat.com/show_bug.cgi?id=1567245 https://www.npmjs.com/advisories/607 • CWE-665: Improper Initialization •

https://notcve.org/view.php?id=CVE-2020-14312
A flaw was found in the default configuration of dnsmasq, as shipped with Fedora versions prior to 31 and in all versions Red Hat Enterprise Linux, where it listens on any interface and accepts queries from addresses outside of its local subnet. In particular, the option `local-service` is not enabled. Running dnsmasq in this manner may inadvertently make it an open resolver accessible from any address on the internet. This flaw allows an attacker to conduct a Distributed Denial of Service (DDoS) against other systems. Se encontró un fallo en la configuración predeterminada de dnsmasq, como es enviado con Fedora versiones anteriores a 31 y en todas las versiones de Red Hat Enterprise Linux, donde escucha en cualquier interfaz y acepta consultas de direcciones fuera de su subred local. • https://bugzilla.redhat.com/show_bug.cgi?id=1851342 • CWE-284: Improper Access Control •

https://notcve.org/view.php?id=CVE-2018-1111
DHCP packages in Red Hat Enterprise Linux 6 and 7, Fedora 28, and earlier are vulnerable to a command injection flaw in the NetworkManager integration script included in the DHCP client. A malicious DHCP server, or an attacker on the local network able to spoof DHCP responses, could use this flaw to execute arbitrary commands with root privileges on systems using NetworkManager and configured to obtain network configuration using the DHCP protocol. Los paquetes DHCP en Red Hat Enterprise Linux 6 y 7, Fedora 28 y anteriores son vulnerables a un error de inyección de comandos en el script de integración NetworkManager incluido en el cliente DHCP. Un servidor DHCP malicioso o un atacante en la red ocal capaz de suplantar respuestas DHCP podría emplear este error para ejecutar comandos arbitrarios con privilegios root en sistemas que emplean NetworkManager y se configuran para obtener la configuración de red mediante el protocolo de configuración dinámica de host (DHCP). A command injection flaw was found in the NetworkManager integration script included in the DHCP client packages in Red Hat Enterprise Linux. • https://www.exploit-db.com/exploits/44652 https://www.exploit-db.com/exploits/44890 https://github.com/kkirsche/CVE-2018-1111 https://github.com/knqyf263/CVE-2018-1111 http://www.securityfocus.com/bid/104195 http://www.securitytracker.com/id/1040912 https://access.redhat.com/errata/RHSA-2018:1453 https://access.redhat.com/errata/RHSA-2018:1454 https://access.redhat.com/errata/RHSA-2018:1455 https://access.redhat.com/errata/RHSA-2018:1456 https://access.redhat.com&#x • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
