CVE-2017-12613 – apr: Out-of-bounds array deref in apr_time_exp*() functions
https://notcve.org/view.php?id=CVE-2017-12613
When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input. Cuando las funciones apr_time_exp*() o apr_os_exp_time*() se invocan con un valor del campo no válido en Apache Portable Runtime APR 1.6.2 y anteriores, se podría acceder a la memoria fuera de límites convirtiendo este valor en un valor apr_time_exp_t, revelando potencialmente el contenido de otro valor de memoria dinámica estática. También podría desembocar en la terminación del programa, representando una vulnerabilidad de divulgación de información o de denegación de servicio en aplicaciones que llaman a esas funciones APR con entradas externas no validadas. An out-of-bounds array dereference was found in apr_time_exp_get(). An attacker could abuse an unvalidated usage of this function to cause a denial of service or potentially lead to data leak. • http://www.apache.org/dist/apr/Announcement1.x.html http://www.openwall.com/lists/oss-security/2021/08/23/1 http://www.securityfocus.com/bid/101560 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2017:3270 https://access.redhat.com/errata/RHSA-2017:3475 https://access.redhat.com/errata/RHSA-2017:3476 https://access.redhat.com/errata/RHSA-2017:3477 https://access.redhat.com/errata/RHSA-2018:0316 https://access.redhat.com/errata/RHSA • CWE-125: Out-of-bounds Read •
CVE-2017-7793 – Mozilla: Use-after-free with Fetch API (MFSA 2017-22)
https://notcve.org/view.php?id=CVE-2017-7793
A use-after-free vulnerability can occur in the Fetch API when the worker or the associated window are freed when still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada en la API Fetch cuando el trabajador o la ventana asociada se liberan mientras siguen en uso, lo que resulta en un cierre inesperado potencialmente explotable. La vulnerabilidad afecta a Firefox en versiones anteriores a la 56, Firefox ESR en versiones anteriores a la 52.4 y Thunderbird en versiones anteriores a la 52.4. • http://www.securityfocus.com/bid/101055 http://www.securitytracker.com/id/1039465 https://access.redhat.com/errata/RHSA-2017:2831 https://access.redhat.com/errata/RHSA-2017:2885 https://bugzilla.mozilla.org/show_bug.cgi?id=1371889 https://lists.debian.org/debian-lts-announce/2017/11/msg00000.html https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3987 https://www.debian.org/security/2017/dsa-4014 https://www.mozilla.org/security/advisor • CWE-416: Use After Free •
CVE-2017-2582 – keycloak: SAML request parser replaces special strings with system properties
https://notcve.org/view.php?id=CVE-2017-2582
It was found that while parsing the SAML messages the StaxParserUtil class of keycloak before 2.5.1 replaces special strings for obtaining attribute values with system property. This could allow an attacker to determine values of system properties at the attacked system by formatting the SAML request ID field to be the chosen system property which could be obtained in the "InResponseTo" field in the response. Se ha descubierto que cuando se analizan los mensajes SAML, la clase StaxParserUtil de keycloak en versiones anteriores a la 2.5.1 reemplaza cadenas especiales para obtener valores de atributos con la propiedad del sistema. Esto podría permitir que un atacante determine valores de las propiedades del sistema en el sistema atacado formateando el campo ID de petición SAML para que sea la propiedad del sistema elegida, la cual se puede obtener en el campo "InResponseTO" en la respuesta. It was found that while parsing the SAML messages the StaxParserUtil class of Picketlink replaces special strings for obtaining attribute values with system property. • http://www.securityfocus.com/bid/101046 http://www.securitytracker.com/id/1041707 https://access.redhat.com/errata/RHSA-2017:2808 https://access.redhat.com/errata/RHSA-2017:2809 https://access.redhat.com/errata/RHSA-2017:2810 https://access.redhat.com/errata/RHSA-2017:2811 https://access.redhat.com/errata/RHSA-2017:3216 https://access.redhat.com/errata/RHSA-2017:3217 https://access.redhat.com/errata/RHSA-2017:3218 https://access.redhat.com/errata/RHSA-2017:3219 https: • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-201: Insertion of Sensitive Information Into Sent Data •
CVE-2017-7536 – hibernate-validator: Privilege escalation when running under the security manager
https://notcve.org/view.php?id=CVE-2017-7536
In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue(). En Hibernate Validator 5.2.x anteriores a 5.2.5 final, 5.3.x y 5.4.x, se ha detectado que cuando los permisos reflectivos del gestor de seguridad, el cual accede a los miembros privados de la clase, se conceden a Hibernate Validator, podría ocurrir un escalado de privilegios. Permitiendo que el código de llamada acceda a esos miembros privados sin ningún permiso, el atacante podría validar una instancia no válida y acceder al valor del miembro privado mediante ConstraintViolation#getInvalidValue().

CVE-2017-1000253 – Linux Kernel PIE Stack Buffer Corruption Vulnerability
https://notcve.org/view.php?id=CVE-2017-1000253
Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary.
