In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations. En PHP versiones 7.2.x por debajo de 7.2.26, versiones 7.3.x por debajo de 7.3.13 y 7.4.0, las funciones de extensión bcmath de PHP en algunos sistemas, incluyendo Windows, pueden ser engañadas para que lean más allá del espacio asignado al suministrarle cadenas que contengan caracteres que el sistema operativo identifica como numéricos pero no son números ASCII. Esto puede ser leído para revelar el contenido de algunas ubicaciones de memoria. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00036.html https://bugs.php.net/bug.php?id=78878 https://lists.debian.org/debian-lts-announce/2019/12/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/N7GCOAE6KVHYJ3UQ4KLPLTGSLX6IRVRN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XWRQPYXVG43Q7DXMXH6UVWMKWGUW552F https://seclists.org/bugtraq/2020/Feb/27 https://seclists.org/bugtraq/2020/Feb/31 ht • CWE-125: Out-of-bounds Read •
CVSS: 5.9EPSS: 0%CPEs: 16EXPL: 1CVE-2019-11045 – DirectoryIterator class silently truncates after a null byte
https://notcve.org/view.php?id=CVE-2019-11045
In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access. En PHP versiones 7.2.x por debajo de 7.2.26, versiones 7.3.x por debajo de 7.3.13 y 7.4.0, la clase DirectoryIterator de PHP acepta nombres de archivo con \0 byte insertado y los trata como terminando en ese byte. Esto podría conllevar a vulnerabilidades de seguridad, por ejemplo en aplicaciones que comprueban las rutas a las que se permite acceder al código. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00036.html https://bugs.php.net/bug.php?id=78863 https://lists.debian.org/debian-lts-announce/2019/12/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/N7GCOAE6KVHYJ3UQ4KLPLTGSLX6IRVRN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XWRQPYXVG43Q7DXMXH6UVWMKWGUW552F https://seclists.org/bugtraq/2020/Feb/27 https://seclists.org/bugtraq/2020/Feb/31 ht • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-170: Improper Null Termination •

https://notcve.org/view.php?id=CVE-2019-19906
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl. cyrus-sasl (también se conoce como Cyrus SASL) versión 2.1.27, presenta una escritura fuera de límites conllevando a una denegación de servicio remota no autenticada en OpenLDAP por medio de un paquete LDAP malformado. El bloqueo de OpenLDAP es causado en última instancia por un error por un paso en la función _sasl_add_string en el archivo common.c en cyrus-sasl. • http://seclists.org/fulldisclosure/2020/Jul/23 http://seclists.org/fulldisclosure/2020/Jul/24 http://www.openwall.com/lists/oss-security/2022/02/23/4 https://github.com/cyrusimap/cyrus-sasl/issues/587 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2019/12/msg00027.h • CWE-193: Off-by-one Error CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •

CVSS: 7.5EPSS: 1%CPEs: 7EXPL: 1CVE-2019-15961 – Clam AntiVirus (ClamAV) Software Email Parsing Vulnerability
https://notcve.org/view.php?id=CVE-2019-15961
A vulnerability in the email parsing module Clam AntiVirus (ClamAV) Software versions 0.102.0, 0.101.4 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to inefficient MIME parsing routines that result in extremely long scan times of specially formatted email files. An attacker could exploit this vulnerability by sending a crafted email file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to scan the crafted email file indefinitely, resulting in a denial of service condition. Una vulnerabilidad en el módulo de análisis de correo electrónico de Clam AntiVirus (ClamAV) Software versiones 0.102.0, 0.101.4 y anteriores, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio en un dispositivo afectado. • https://bugzilla.clamav.net/show_bug.cgi?id=12380 https://lists.debian.org/debian-lts-announce/2020/02/msg00016.html https://quickview.cloudapps.cisco.com/quickview/bug/CSCvr56010 https://security.gentoo.org/glsa/202003-46 https://usn.ubuntu.com/4230-2 • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
