CVSS: 5.5EPSS: 0%CPEs: 30EXPL: 1CVE-2016-1837 – libxml2: Heap use-after-free in htmlPArsePubidLiteral and htmlParseSystemiteral
https://notcve.org/view.php?id=CVE-2016-1837
Multiple use-after-free vulnerabilities in the (1) htmlPArsePubidLiteral and (2) htmlParseSystemiteral functions in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allow remote attackers to cause a denial of service via a crafted XML document. Múltiples vulnerabilidades de uso después de liberación de memoria en las funciones (1) htmlPArsePubidLiteral y (2) htmlParseSystemiteral en libxml2 en versiones anteriores a 2.9.4, como se utilizan en Apple iOS en versiones anteriores a 9.3.2, OS X en versiones anteriores a 10.11.5, tvOS en versiones anteriores a 9.2.1 y watchOS en versiones anteriores a 2.2.1, permiten a atacantes remotos provocar una denegación de servicio a través de un documento XML manipulado. • http://lists.apple.com/archives/security-announce/2016/May/msg00001.html http://lists.apple.com/archives/security-announce/2016/May/msg00002.html http://lists.apple.com/archives/security-announce/2016/May/msg00003.html http://lists.apple.com/archives/security-announce/2016/May/msg00004.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http • CWE-416: Use After Free •
CVSS: 7.5EPSS: 1%CPEs: 9EXPL: 0CVE-2016-3705 – libxml2: stack overflow before detecting invalid XML file
https://notcve.org/view.php?id=CVE-2016-3705
The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references. Las funciones (1) xmlParserEntityCheck y (2) xmlParseAttValueComplex en parser.c en libxml2 2.9.3 no hace seguimiento de manera adecuada de la profundidad de recursividad, lo que permite a atacantes dependientes del contexto provocar una denegación de servicio (consumo de pila y caída de la aplicación) a través de un documento XML manipulado que contiene un gran número de referencias de entidades anidadas. Missing incrementation of recursion depth counter were found in the xmlParserEntityCheck() and xmlParseAttValueComplex() functions used for parsing XML data. An attacker could launch a Denial of Service attack by passing specially crafted XML data to an application, forcing it to crash due to stack exhaustion. • http://lists.opensuse.org/opensuse-updates/2016-05/msg00055.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00127.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://seclists.org/fulldisclosure/2016/May/10 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.securityfocus.com/bid/89854& • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •
CVSS: 7.5EPSS: 0%CPEs: 28EXPL: 0CVE-2016-3627 – libxml2: stack exhaustion while parsing xml files in recovery mode
https://notcve.org/view.php?id=CVE-2016-3627
The xmlStringGetNodeList function in tree.c in libxml2 2.9.3 and earlier, when used in recovery mode, allows context-dependent attackers to cause a denial of service (infinite recursion, stack consumption, and application crash) via a crafted XML document. La función xmlStringGetNodeList en tree.c en libxml2.2.9.3 y versiones anteriores, cuando se utiliza en modo de recuperación, permite a atacantes dependientes del contexto provocar una denegación de servicio (bucle infinito, consumo de pila y caída de la aplicación) a través de un docuumento XML manipulado. Missing recursive loop detection checks were found in the xmlParserEntityCheck() and xmlStringGetNodeList() functions of libxml2, causing application using the library to crash by stack exhaustion while building the associated data. An attacker able to send XML data to be parsed in recovery mode could launch a Denial of Service on the application. libxml versions prior to 2.9.3 suffer from a stack overflow vulnerability when parsing a malicious file. • http://lists.opensuse.org/opensuse-updates/2016-05/msg00055.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00127.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://seclists.org/fulldisclosure/2016/May/10 http://www.openwall.com/lists/oss-security/2016/03/21/2 http://www.openwall.com/lists/oss-security/2016/03/21/3 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016& • CWE-674: Uncontrolled Recursion •
