contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation. contrib/slapd-modules/nops/nops.c en OpenLDAP hasta la versión 2.4.45, cuando el módulo nops y la capa memberof están activados, intenta liberar un búfer que se había asignado en la pila, lo que permite que los atacantes remotos provoquen una denegación de servicio (cierre inesperado de slapd) mediante una operación member MODDN. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00058.html http://www.openldap.org/its/index.cgi/Incoming?id=8759 https://kc.mcafee.com/corporate/index?page=content&id=SB10365 https://www.oracle.com/security-alerts/cpuapr2022.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-9287 – openldap: Double free vulnerability in servers/slapd/back-mdb/search.c
https://notcve.org/view.php?id=CVE-2017-9287
servers/slapd/back-mdb/search.c in OpenLDAP through 2.4.44 is prone to a double free vulnerability. A user with access to search the directory can crash slapd by issuing a search including the Paged Results control with a page size of 0. servers/slapd/back-mdb/search.c en OpenLDAP hasta la versión 2.4.44 es propenso a una doble vulnerabilidad de liberación de memoria. Un usuario con acceso para buscar en el directorio puede hacer que slapd deje de funcionar al emitir una búsqueda que incluya el control Paged Results con un tamaño de página de 0. A double-free flaw was found in the way OpenLDAP's slapd server using the MDB backend handled LDAP searches. A remote attacker with access to search the directory could potentially use this flaw to crash slapd by issuing a specially crafted LDAP search query. • http://www.debian.org/security/2017/dsa-3868 http://www.openldap.org/its/?findid=8655 http://www.securityfocus.com/bid/98736 http://www.securitytracker.com/id/1038591 https://access.redhat.com/errata/RHSA-2017:1852 https://bugs.debian.org/863563 https://kc.mcafee.com/corporate/index?page=content&id=SB10365 https://www.oracle.com/security-alerts/cpuapr2022.html https://access.redhat.com/security/cve/CVE-2017-9287 https://bugzilla.redhat.com/show_bug.cgi?id=1456712 • CWE-415: Double Free CWE-416: Use After Free •
CVE-2016-4472
https://notcve.org/view.php?id=CVE-2016-4472
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716. La protección de desbordamiento en Expat es eliminada por los compiladores con ciertos ajustes de optimización, lo que permite a atacantes remotos provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de datos XML manipulados.

CVE-2016-0718 – expat: Out-of-bounds heap read on crafted input causing crash
https://notcve.org/view.php?id=CVE-2016-0718
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. Expat permite a atacantes dependientes del contexto provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de un documento de entrada mal formado, lo que desencadena un desbordamiento de buffer. An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application. • http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-08 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
