In FreeBSD 11.3-STABLE before r350217, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, due to insufficient initialization of memory copied to userland in the freebsd32_ioctl interface, small amounts of kernel memory may be disclosed to userland processes. This may allow an attacker to leverage this information to obtain elevated privileges either directly or indirectly. En FreeBSD versión 11.3-STABLE anterior a r350217, versión 11.3-RELEASE anterior a 11.3-RELEASE-p1, y versión 11.2-RELEASE anterior a 11.2-RELEASE-p12, debido a una insuficiente inicialización de la memoria copiada hacia userland en la interfaz de freebsd32_ioctl, pequeñas cantidades de memoria del kernel pueden ser divulgadas a los procesos de userland. Esto puede permitir a un atacante aprovechar esta información para obtener privilegios elevados tanto directa como indirectamente. • http://packetstormsecurity.com/files/153749/FreeBSD-Security-Advisory-FreeBSD-SA-19-14.freebsd32.html https://security.FreeBSD.org/advisories/FreeBSD-SA-19:14.freebsd32.asc https://security.netapp.com/advisory/ntap-20190814-0003 • CWE-665: Improper Initialization •

This causes an incorrect signal to be raised leading to a write after free of kernel memory allowing a malicious user to gain root privileges or escape a jail. En FreeBSD versión 12.0-STABLE anterior a r349805, versión 12.0-RELEASE anterior a 12.0-RELEASE-p8, versión 11.3-STABLE anterior a r349806, versión 11.3-RELEASE anterior a 11.3-RELEASE-p1, y versión 11.2-RELEASE anterior a 11.2-RELEASE-p12, el código que maneja el cierre de un descriptor creado por posix_openpt no puede deshacer una configuración de la señal. Esto causa que una señal incorrecta sea generada conduciendo a una escritura después de liberar la memoria del kernel, lo que permite a un usuario malicioso alcanzar privilegios de root o escapar de una jaula.. • http://packetstormsecurity.com/files/153748/FreeBSD-Security-Advisory-FreeBSD-SA-19-13.pts.html https://security.FreeBSD.org/advisories/FreeBSD-SA-19:13.pts.asc https://security.netapp.com/advisory/ntap-20190814-0003 • CWE-416: Use After Free •
CVSS: 8.1EPSS: 0%CPEs: 28EXPL: 0CVE-2019-9498 – The implementations of EAP-PWD in hostapd EAP Server do not validate the scalar and element values in EAP-pwd-Commit
https://notcve.org/view.php?id=CVE-2019-9498
The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may be able to use invalid scalar/element values to complete authentication, gaining session key and network access without needing or learning the password. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected. Las implementaciones del componente EAP-PWD en hostapd en EAP Server, cuando se construyen contra una biblioteca criptográfica sin comprobación explícita en elementos importados, no comprueban los valores escalares y de elementos en EAP-pwd-Commit. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html https://lists.debian.org/debian-lts-announce/2019/07/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TDOZGR3T7FVO5JSZWK2QPR7AOFIEJTIZ https://seclists.org/bugtraq& • CWE-287: Improper Authentication CWE-346: Origin Validation Error •

CVSS: 5.9EPSS: 0%CPEs: 55EXPL: 3CVE-2019-6111 – OpenSSH SCP Client - Write Arbitrary Files
https://notcve.org/view.php?id=CVE-2019-6111
An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). • https://www.exploit-db.com/exploits/46516 https://www.exploit-db.com/exploits/46193 http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00058.html http://www.openwall.com/lists/oss-security/2019/04/18/1 http://www.openwall.com/lists/oss-security/2022/08/02/1 http://www.securityfocus.com/bid/106741 https://access.redhat.com/errata/RHSA-2019:3702 https://bugzilla.redhat.com/show_bug.cgi?id=1677794 https://cert-portal.siemens.com/productcert/pdf/ssa-412672&# • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
