CVE-2020-8794 – OpenSMTPD - OOB Read Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2020-8794
OpenSMTPD before 6.6.4 allows remote code execution because of an out-of-bounds read in mta_io in mta_session.c for multi-line replies. Although this vulnerability affects the client side of OpenSMTPD, it is possible to attack a server because the server code launches the client code during bounce handling. OpenSMTPD versiones anteriores a 6.6.4, permite una ejecución de código remota debido a una lectura fuera de límites en la función mta_io en el archivo mta_session.c para respuestas multilínea. Aunque esta vulnerabilidad afecta al lado del cliente de OpenSMTPD, es posible atacar a un servidor porque el código del servidor inicia el código del cliente durante el manejo de saltos. • https://www.exploit-db.com/exploits/48185 https://www.exploit-db.com/exploits/48140 http://packetstormsecurity.com/files/156633/OpenSMTPD-Out-Of-Bounds-Read-Local-Privilege-Escalation.html http://seclists.org/fulldisclosure/2020/Feb/32 http://www.openwall.com/lists/oss-security/2020/02/26/1 http://www.openwall.com/lists/oss-security/2020/03/01/1 http://www.openwall.com/lists/oss-security/2020/03/01/2 http://www.openwall.com/lists/oss-security/2021/05/04/7 https: • CWE-125: Out-of-bounds Read •
CVE-2020-8793 – OpenSMTPD 6.6.3 - Arbitrary File Read
https://notcve.org/view.php?id=CVE-2020-8793
OpenSMTPD before 6.6.4 allows local users to read arbitrary files (e.g., on some Linux distributions) because of a combination of an untrusted search path in makemap.c and race conditions in the offline functionality in smtpd.c. OpenSMTPD versiones anteriores a 6.6.4, permite a usuarios locales leer archivos arbitrarios (por ejemplo, en algunas distribuciones de Linux) debido a una combinación de una ruta de búsqueda no confiable en el archivo makemap.c y unas condiciones de carrera en la funcionalidad offline en el archivo smtpd.c. • https://www.exploit-db.com/exploits/48139 http://seclists.org/fulldisclosure/2020/Feb/28 http://www.openwall.com/lists/oss-security/2020/02/24/4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OPH4QU4DNVHA7ACFXMYFCEP5PSXXPN4E https://usn.ubuntu.com/4294-1 https://www.openbsd.org/security.html • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-426: Untrusted Search Path •

CVE-2015-9542
https://notcve.org/view.php?id=CVE-2015-9542
add_password in pam_radius_auth.c in pam_radius 1.4.0 does not correctly check the length of the input password, and is vulnerable to a stack-based buffer overflow during memcpy(). An attacker could send a crafted password to an application (loading the pam_radius library) and crash it. Arbitrary code execution might be possible, depending on the application, C library, compiler, and other factors. La función add_password en el archivo pam_radius_auth.c en pam_radius versión 1.4.0, no verifica correctamente la longitud de la contraseña de entrada y es vulnerable a un desbordamiento del búfer en la región stack de la memoria durante la función memcpy(). Un atacante podría enviar una contraseña diseñada hacia una aplicación (cargando la biblioteca pam_radius) y bloquearla. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-9542 https://github.com/FreeRADIUS/pam_radius/commit/01173ec2426627dbb1e0d96c06c3ffa0b14d36d0 https://lists.debian.org/debian-lts-announce/2020/02/msg00023.html https://lists.debian.org/debian-lts-announce/2020/08/msg00000.html https://usn.ubuntu.com/4290-1 https://usn.ubuntu.com/4290-2 • CWE-787: Out-of-bounds Write •
CVE-2020-9327 – sqlite: NULL pointer dereference and segmentation fault because of generated column optimizations
https://notcve.org/view.php?id=CVE-2020-9327
In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and segmentation fault because of generated column optimizations. En SQLite versión 3.31.1, la función isAuxiliaryVtabOperator permite a atacantes desencadenar una desreferencia del puntero NULL y un fallo de segmentación debido a las optimizaciones de columna generadas. A NULL pointer dereference was found in SQLite in the way it executes select statements with column optimizations. An attacker who is able to execute SQL statements can use this flaw to crash the application. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://security.gentoo.org/glsa/202003-16 https://security.netapp.com/advisory/ntap-20200313-0002 https://usn.ubuntu.com/4298-1 https://www.oracle.com/security-alerts/cpuApr2021.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpujul2020.html https://www.oracle.com/security-alerts/cpuoct2020.html https://www.sqlite.org/cgi/src/info/4374860b29383380 https://www.sqlite. • CWE-476: NULL Pointer Dereference •
