CVE-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 •
CVE-2020-14312
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 •
CVE-2019-11328
https://notcve.org/view.php?id=CVE-2019-11328
An issue was discovered in Singularity 3.1.0 to 3.2.0-rc2, a malicious user with local/network access to the host system (e.g. ssh) could exploit this vulnerability due to insecure permissions allowing a user to edit files within `/run/singularity/instances/sing/<user>/<instance>`. The manipulation of those files can change the behavior of the starter-suid program when instances are joined resulting in potential privilege escalation on the host. Se encontró un problema en Singularity versión 3.1.0 hasta la 3.2.0-rc2, un usuario malicioso con acceso local de red hacia el sistema host (por ejemplo, ssh) podría atacar esta vulnerabilidad debido a permisos no seguros que permiten a un usuario editar archivos dentro de `/run/singularity/instances/sing//`. La manipulación de esos archivos puede cambiar el comportamiento del programa starter-suid cuando las peticiones se unen, lo que conlleva a una posible escalada de privilegios en el host. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00059.html http://www.openwall.com/lists/oss-security/2019/05/16/1 http://www.securityfocus.com/bid/108360 https://github.com/sylabs/singularity/releases/tag/v3.2.0 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5O3TPL5OOTIZEI4H6IQBCCISBARJ6WL3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject& • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2019-11884 – kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command
https://notcve.org/view.php?id=CVE-2019-11884
The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character. La función do_hidp_sock_ioctl en net/bluetooth/hidp/sock.c en el kernel de Linux, versiones anteriores a 5.0.15, permite a un usuario local obtener información potencialmente sensible de la memoria de la pila del kernel a través de un comando HIDPCONNNADD, ya que un campo de nombre puede no terminar con un carácter ` \0'. A flaw was found in the Linux kernel's implementation of the Bluetooth Human Interface Device Protocol (HIDP). A local attacker with access permissions to the Bluetooth device can issue an IOCTL which will trigger the do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c.c. This function can leak potentially sensitive information from the kernel stack memory via a HIDPCONNADD command because a name field may not be correctly NULL terminated. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://www.securityfocus.com/bid/108299 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://access.redhat.com/errata/RHSA-2020:0740 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.15 https://g • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2019-11831
https://notcve.org/view.php?id=CVE-2019-11831
The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3 does not prevent directory traversal, which allows attackers to bypass a deserialization protection mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL. El paquete PharStreamWrapper (también conocido como phar-stream-wrapper), versiones 2.x anteriores a 2.1.1 y 3.x anteriores a 3.1.1 para TYPO3, no impide el salto de directorio, lo que permite a los atacantes eludir un mecanismo de protección de deserialización, como lo demuestra una URL phar:///path/bad.phar/../good.phar. • http://www.securityfocus.com/bid/108302 https://github.com/TYPO3/phar-stream-wrapper/releases/tag/v2.1.1 https://github.com/TYPO3/phar-stream-wrapper/releases/tag/v3.1.1 https://lists.debian.org/debian-lts-announce/2019/05/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/65ODQHDHWR74L6TCAPAQR5FQHG6MCXAW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6QDJVUJPUW3RZ4746SC6BX4F4T6ZXNBH https://lists.fedoraproject. • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-502: Deserialization of Untrusted Data •
